Mac Pro USB issue

I have a weird situation. I have a Mac Pro 8 core 3.0Ghz with 13GB RAM, 4 SATA internal drives, 2 USB external 500 Western Digital Drives. I use bay one of the sata for OSX Tiger and Bay 2 for OSX Leopard (both purchased versions). The problem is when I'm in Tiger the USB drives have a through put of about 3MB and when booted in Leopard they have a through put of about 24MB. I can only guess that it's a driver problem, but I haven't been able to find anything about the fix. I did find that the WD USB Drives have a problem with speed. These WD drives are USB and SATA. When using them as SATA drives they work fine on both versions of OSX. The problem is I need the SATA connections for other drives and just want to use the WD drives as backup. Has anyone got any ideas why the drives perform normally under Leopard and not under Tiger?

Hi southwos,
That certainly is a strange one...
I have heard of several USB issues pertaining to tiger updates, noteably, 10.4.11. It would seem some USB drivers were updated to fix several bugs, but inadvertantly, caused others. The solution it seems, is to rollback to 10.4.9.
The symptoms of this 'unexpected feature' (sic) are that some USB devices seem to operate at USB1.1 speeds.
This only affects a small number of devices, and its the chipsets in said devices that have the conflict.
Certainly hope i have been of help
Cheers
Bryza

Mac Pro Display Issue

Mac Pro Display Issue - Unexpectedly Sleeps and Freezes
Just since a couple of days my Mac Pro desktop has been having display issues. Unexpectedly the screens go into sleep mode, it turns black and freezes, the computer doesnot respond to the keyboard or mouse.
At first I thought this was related to Chrome, and switched to Firefox, but the computer is still having the same issue. I have to shut down and restart each time it gets stuck.
I even went into preferences and changed the energy saver settings to "Never" allow display or harddrive to sleep. But this problem is stil happening.
Does anyone have the same problems? Or a solution?

I cleaned out my mac with compressed air, it was dusty, but the display flickering happened again.
So I followed your advice and installed:
Temperature Monitor
http://www.bresink.de/osx/TemperatureMonitor.html
Which showed that my memory module 1B and 2B were 70 - 75'C(160 -167'F). There was no reading for the graphic card so I couldn't tell if that was over heating.
Then I installed:
smc fan controller
http://www.macupdate.com/app/mac/23049/smcfancontrol
and increased the memory_cpu fan speed which lowered the temperature of the ram to 60'C (143'F).
I even changed this ram's placement and put it in different slots.This ram was the same temperature in the new placements.
Also this is the kingston 2gb ram without heatsinks. Ive used it for 1.5 yrs, and this is the first time its giving me these problems.
Do you know how I can check if the graphic card is over heating? or is the problem just with the ram?
Thank you for all your help!

Mac Pro USB and FW800 ports not working

I've been reading tons of forum entries in the Apple Support Community and in other forums. Nothing seems to answer quite what's going on with my Mac Pro Tower.
Here are the details and steps taken up to now:
- I'm running a Mac Pro Tower (MacPro 3,1, 2x 2,8GHz Quad Core, Early 2008 model), currently running OS 10.6.8
- I moved before the holidays in December and left my computer unplugged for over month while away. Didn't have any issues before the move.
- up until the last couple of weeks, I had actually been running on Leopard (yes, I'm a luddite!, please, no teasing )
- I was trying to update my ipod touch's iOS and kept getting errors preventing it from completing the process. At first I thought it was an ipod app causing the issue after having read a few threads on that topic...
- Also, on startup, the Mac started searching for a Bluetooth keyboard, of which I don't have, and would not detect my usb keyboard. I would disconnect and reconnect the keyboard and the majority of the time, the Mac would then recognize my USB keyboard.
- I decided to upgrade to Snow Leopard, which didn't help with the iPod update. I did not do a clean install.
- Then I noticed that my USB stick wasn't working and tried it in all the usb ports (except the ones on the keyboard)
- Also, I had removed and then reinstalled printer and scanner drivers for my All-in-one printer. After this I kept getting constant communication errors between the mac and the printer via the usb port, although I was able to print a test page.
- I've used Hardware Test once which didn't detect any issue.
- I reset the SMC
- I reset the PRAM, and for a few seconds I was able to read from my USB stick, then never again, even after another PRAM reset.
- I've cleaned the whole inside of the computer and checked for loose cables. Cables are in so tight it's so hard to loosen them!
- I now tested all the ports:
     ∞ the 2 front and 3 back USB ports are unresponsive to my usb key and to my VoyagerQ dock
     ∞ the front and back FW800 ports are unresponsive to my VoyagerQ dock
     ∞ However, the keyboard works in any fo the back ports and my USB stick is recorgnized by the USB port of the keyboard.
     ∞ I also plugged in my Logitech webcam into the keyboard and it works there but not in any other port.
     ∞ When I plug in USB powered speakers into any of the ports, they work fine
     ∞ And the FW400 ports are also working fine with my VoyagerQ dock
- a few times, including once today, my mac restarted by itself. The times before today, I thought it was because I was sort of moving back the computer in place, but today I was nowhere near the computer.
So what does this all mean? Should I do a clean install of the Mac OS? Or is it a problem with my Logic Board?
Any insight please would be helpful. I had Apple Care and missed the reminder to renew it so I really hoping not to spend more money than necessary.

Thanks Grant,
The battery is a start and something inexpensive to replace.
I did do a PRAM reset (command + option + P + R) and was able to hear the chime 4 times. I tried resetting it a number of times over the past week, as well as yesterday with no success in reviving the USB ports. But isn't it weird that my USB powered speakers work by plugging them in any USB port (with the mini jack pugged in the back or front earphone plug)?
I did not use the USB ports on the keyboard until yesterday, so that is not the cause of the other USB and FW800 ports failing. But I'll follow your suggestion and not use them except for the mouse.
Another weird thing that happened yesterday, I have 16GB of RAM and I spent all day trying to troubleshoot a RAM issue that is magically fixed after leaving the computer on overnight to do an extended Hardware Test. The issue was:
- Only 8 RAMS were being recognized
- a red LED light appeared on the top riser
- first I thought I had isolated the faulty RAM bar, and then a second one
- Then going pair by pair again, I no longer saw the LED light
- Put back all 8 bars, only 8 GB of RAM recognized
- Left computer overnight running Hardware test (said it took almost 3 hours, with no errors)
- Now all 16 GB are recognized!
Thanks again for the tips

Mac Pro Boot Issue

Mac Pro - "Quad", 2 X 2.66Ghz; 5GB RAM; OS X 10.5.6
Mac Pro will not boot. It powers up to the grey Apple logo screen. The progress circle spins for about 3 seconds, then powers itself off.
This past week I came back from two weeks off. The first morning back I noticed my Mac was sluggish at times and freezing for a few seconds here and there. When Time Machine backups would kick in, the whole system would be unresponsive for minutes at a time. After turning off all other equipment in my office, I could detect a tell-tale "click click, spin" type noise coming from one of my two internal drives (one for OS and a second for backups).
I tracked the noise to the boot drive and guessing it was about to go out, I ordered a replacement Samsung Spinpoint 750GB. Good thing, because the next day when I came in to work my machine was having worse problems. IF it would boot, it would hang after a few minutes of use. If it would not boot, it would power up to the grey Apple logo, the progress circle would spin a few seconds, the power itself off.
I waited another day and the new drive arrived. I pulled the old OS drive, installed the new one, then dumped our standardized clone image on the drive (using CCC). After the clone was complete, I booted up on the drive, tested it out for a couple of hours and verified that it was working as expected. Next I copied data over to my drive from my backup drive. Everything looked fine.
Three days later, I come in to find my Mac will no longer boot. Grey Apple logo, spinning, etc.. I power off and boot from my external diagnostic drive (OS X 10.5.5). It will not boot. I remove both internal drives and try another boot from the external diagnostic drive. It boots up fine. Shutdown. Remove the backup drive (drive bay 2) and try to reboot from the diag drive once again. It will not boot. Remove the OS drive (drive bay 1) and it boots to the diagnostic drive fine (note: no internal drives are installed at this point). Shutdown. Install the OS drive into drive bay 2 and it then boots to the diagnostic drive just fine.
So now I have booted to my external diag drive and can see that the OS drive is showing on the Desktop; however a pop-up error stating there is a problem has appeared. I try to verify the OS drive using Disk Utility and it stops about 2 seconds into the process with a "Filesystem verify or repair failed" error. The OS drive will then not mount.
I restart booting back to the external diag drive. The OS drive shows up on the Desktop with the same pop-up error message as before.
I run Tech Tool Pro from the diag drive and it comes back with a File Structure error of "Type List Offset Is Invalid" and "No method for Tech Tool Pro to repair a corrupt file". I have a surface scan and drive hardware test running now, but on a 750GB it will be a WHILE.
So here is my predicament... I can understand my original OS drive having problems. It was at least 3 yrs old and has been run quite hard. But what are the odds that I would replace it with a brand new drive running a verified to be good cloned disk image AND have almost the exact same boot issues on the new drive that I had on the old one?
I have taken my original OS drive and hooked it up to external cases and sata-to-usb adapters to make sure that it was actually dead and it is. It will not spin up properly and makes lots of clicking noises. However, having a similar boot issue with a brand new drive has me worried something may be wrong with the Mac Pro hardware also. The new OS drive ran fine for a few days and only had these problems today.
Any guesses?

Here is my own "cookie cutter" template to this type of problem.
Insure your UPS is working properly and that you have 1300VA to start with.
Run Apple Hardware Test of course.
CCC has been updated so make sure latest (it auto checks probably already).
Do you have Windows? run diagnostics from there, much better.
I settled on WD drives and use WD Diagnostic and has saved a drive.
Avoid Barracudas, seems even their 1TB is also suffering early failures (the 1.5TB was suffering from firmware problem).
Check for reviews and drive upgrade DB on AccelerateYourMac.
http://www.xlr8yourmac.com/
I know the F1 got a lot of early praise but they aren't compatible with Apple Pro RAID card and may have other issues.
If you want a fast low-cost drive, WD Cavair 640GB $69.

I have seen more than a couple of similar stories from people going away for 1-2 weeks and coming home to system that won't work properly. Hopefully people shutdown and unplug, or shutdown and have UPS, but it is strange to say the least.
Resetting SMC is a good idea but best done with 2008 model by leaving it unplugged for a full night 8-12 hrs. and not just 5 minutes. contrary to Apple tech article. For yours, there is a small physical button accessed by pulling drive tray #4 (easier to see if it is on its side and you have flashlight!)

Early 2008 Mac Pro boot issue

I'm having what seems to be a hardware issue with my Mac Pro on booting. The MP boots to either a blue screen or a chunked grey screen (http://gallery.me.com/dwphoto#100036/IMG_1401) and hang. So far, I've tried booting from multiple clones (from 10.5-10.6.6) as well as the Snow Leopard install DVD, reinstalling SL, removed all 3rd party cards and usb/firewire externals, zapped the PRAM, repaired permissions, verified disks. It will boot into Safe Mode without problem. If it hangs on normal boot, all the drives are visible and active over a network. I'm pretty stumped.

They were reluctant? I hope you printed out the Apple article. Unbelievable.
What I would like would be a link at the top of this forum and more direct access (and we all want better organized and search results to KB articles).
There ought to be "newest changes KB" and a Warranty category

Macbook Pro USB issue

Hi All;
I saw lots of discussions about USB problem of Macbook Pro, and i tried maybe all suggestions, i couldnt solve USB issue
I bought my Macbook Pro 13 inc, 500 GB, i5, OS X Lion, 2 days ago and this is my first Mac ...
I cant see my external disk (Philips), Samsung Galaxy S by using USB ports (i tried both USB enterances, but not working).
I checked my Hardware by Apple Hardware Test (extended test done) and it says 'No trouble found'
I checked Utilities and USB devices are not written in the list, only 500 GB SATA disk shown.
I uploaded MacFuse-Tuxera and ntfs-3g-2010 softwares for using USB devices but i cant solve the problem too...
My USB devices are not shown in desktop and utilities lists
How can i solve this problem, my devices work in Windows 7 - PC as usual, but in Macbook Pro, they dont work, please support me. I dont think that it can be hardware problem, Mac is new and devices are ok. Operating systems are different only.
Thanks, Regards.

I solved the problem about Samsung Galaxy S, now i can connect it by changing settings of GALAXY S.
Settings>Applications>Development
Than i plug phone to MAC and now i can see my phone on desktop
I checked my PHILIPS external disk, unfortunatelly it is produced for only Windows operating systems, so i cant use it anymore
My MAC has no USB problem, i can use my 3G USB device too, only Philips external disk failed.
Thanks for your support...

Mac Pro USB ports and bluetooth not working

I have a Mac Pro (early 2008) Quad-Core Intel Xeon, 2.8 GHz, 4GB ram, Airport card, Magic Mouse. Suddenly the keyboard and wired/bluetooth Mouse are unavailable, so it is not possible to control the computer. The only way I can use it is by using Screen Sharing from my MacBook Pro - which is obviously pretty useless except for diagnostics! All the USB ports (front and back, as well as those on the Cinema Display - when connected) are dead. System profiler shows no problem with them, but also shows nothing connected. Bluetooth in menu bar shows as "Bluetooth: not available", and in system profiler shows as "No information found".
I've tried all the usual remedies. Powering off overnight with power cord disconnected, all peripherals disconnected, then booting up again. Holding in the power button for ten seconds when the power cord is disconnected. Obviously I can't reset the pRAM (because the keyboard is not recognised, even before the OS loads). The first couple of times I tried this process, it did bring back the USB ports, even the bluetooth became temporarily available, but soon disappeared again. USB ports died next time I rebooted.
However, in the last couple of days, the process produces no results. No matter how long I leave it disconnected, USB ports are not working and bluetooth is just not there...
I've checked for other threads on this topic, but most other people seem to have issues with either front or back USB ports, or even just one or more individual ports. My problems have only been with all ports or none.
Does anyone have any suggestions to get my MacPro up and running again properly?

Just waking this thread up again in case anyone has had any other ideas.
Since last posting, usb became functional again, (came back on a couple of hours after a restart) and as long as I kept the machine alive, usb would stay alive. Bluetooth came back on briefly, but for most of the time was unavailable. System profiler shows no problems and Console does not report any usb related errors as far as I can see.
After a recent restart, usb disappeared again, and despite numerous restarts and being left on for a couple of days (and subsequently left off for several days) it has not come back. When usb is not working, examining the system profiler (through screen sharing from my macbook) usb shows no errors, but also shows no connected devices. I can charge my ipod nano with any of the usb ports (front or back), so power does not seem to be the issue.
I can't reset pRAM (because the keyboard is not available at boot), but have reset SMC numerous times. Have tried other keyboards, and mice. No joy.
I seem to have run out of ideas. Any suggestions?

Mac Pro Display Issues

I am trying to use three monitors with a Mac Pro with a default Radeon 5770 graphics card, but I am coming across many issues. First, I had to find out that you needed two dual-link DVI adapters if you want to add three monitors. After purchasing one adapter from StarTech for a 30" Dell monitor however, the display is having many issues.
When I first turn the computer on, the display shows "snow". I have to turn the display on and off, but sometimes even this does not get rid of it. Also, the screen will not wake up when the computer wakes up from sleep, although the other DVI monitor attached works perfectly. Finally, the screen will often go into periods of complete black. I can still move the mouse on the other screen, but it jumps around and skips when I move it.
If I want to resolve this issue, should I:
1) Go with Apple's dual-link adapter instead of the StarTech one I am currently using
2) Upgrade the Mac Pro graphics to either the dual 5770 or the single 5870
3) Replace the large dell monitor with an Apple Cinema Display
Or, would none of these solutions even help if this is an unsolvable problem.
Any advice would be greatly appreciated.
Thanks!

That is not quite right. Strictly speaking, it is not three dual-Link adapters that are required, but all adapters must be ACTIVE, POWERED Adapters.
Apple's solution requires their Daul-Link adapters because those are the ones with a USB lead to pick up even more power.
Your initail query tlaks of wanting to connect three monitors, but you have only provided connection details for two.

External desktop drives for early 2008 Mac Pro: USB 2.0 or 3.0 question

I have an early 2008 Mac Pro 3,1 (OS 10.6.8).
I currently have a 1 TB Fantom Drive with USB 2.0 that I use for the Time Machine. I want to get the second external drive to use as a boot drive so I can install & boot from Mountain Lion to use Maya 2014 3D application software that requires the Mountain Lion OS. For all other applications, I want to stick with Snow Leopard (10.6.8), which works well for me.
Most of the searches I've done for external drives have USB 3.0. Some have USB 3.0/2.0.
Questions:
1. Will one of the USB 3.0-only external drives work with my early 2008 Mac Pro 3,1, which is only equipped for USB 2.0? If so, would I need some sort of adapter? (I realize that the speed would still be USB 2.0 speed.)
2. Or do I need to get the USB 3.0/2.0 external drive (which is more expensive)? I am assuming this would not require any adapter.
3. Will I be able to boot from the external drive with Mountain Lion?
Thanks for any help with this.
S

First, many thanks to both Grant Bennet-Alder and The hatter for their fast responses to my questions. I really appreciate this information. Based on your suggestions I did some research in order to better understand the proposed solutions.
Grant Bennet-Alder wrote:
You can add a PCIe card to get these interfaces:
eSATA

1. Does one need to get a separate PCIe card for each interface, or is there one PCIe card for multiple interfaces?
The hatter wrote:
Installing or cloning OS X should be done on SATA II drive bay or external and then moved to the PCIe - depends what card you buy, and some issues are with arrays (no need for system on one).
2. I went to http://www.everymac.com/systems/apple/mac_pro/faq/, which says, "By default, a single 3 Gb/s Serial ATA -- sometimes referred to as SATA 2.0 or SATA II -- hard drive is installed in the first of four bays for all models." I interpret that to mean that SATA II is a in the first bay located on my internal hard drive. Can I create a partition here and install Mountain Lion as a separate system, and then move it to a PCIe SSD?
3. Or, can I install it on my external Falcon Drive (which has a Partition Map Scheme : GUID Partition Table, and which, I believe means it is not a bootable drive). Following that installation could I then move it to the PCIe SSD and boot Mountain Lion from there?
4. Or, if partitioning is an option, can I just clone it to the Falcon Drive for backup?
My apologies for my ignorance. This is not my forte. Thanks for any help you can give.

Pple 24" LED and Mac Pro usb connection problem

Hi,
I'm having issues with my Mac Pro 8 core (2008) connected to an Apple 24" LED. I have a Radeon HD 4870 graphics card installed in the Mac so I can use the Apple LED mini displayport connection. The video works perfectly fine but to use the built-in speakers and iSight in the Apple LED I have to use the USB cables and connect them to the USB sockets of the Mac Pro. This is where the problem seems to be as after a time using the Mac it crashes in a strange manner and I get a few lines of coding and the Mac shuts down on its own. I've used Dr Botts extension cables to extend to reach of the USB cables which I thought maybe the issues and taken this off and I've also unplugged any devices plugged into the extra USB sockets on the Apple LED. I think it's something to do with using the speakers as playing video seems to crash the Mac also but once I unplug the USB cables the video plays fine, but without speaker sound. Has anyone had similar problems and have any solutions?
Thanks in advance.
Alec

I have had no problem at all.
Assume you have considered: http://support.apple.com/kb/TS2400
If you have concerns about possible extension cable reliablity, you might want to consider trying a spare such as this one that is available from the Store: http://store.apple.com/us/product/H6730LL/A/

2011 Mac Pro: USB Bluetooth 4.0 dongle

Hello,
Like many others I have been having Bluetooth connection issues with my Mac Pro. So I bought a $15 USB 4.0 bluetooth dongle. How do I verify that my Mac Pro is using the bluetooth from the USB dongle rather than the internal bluetooth?

Thank you; that is helpful. If possible, I'd like to avoid going in and removing wires, etc. From everything I have read, the bluetooth antenna is very close to and similar-looking to the wifi antenna, so I don't want to mess it up.
I also read elsewhere that if you plug in a USB bluetooth dongle, the Mac Pro will automatically recognize it and start using it. I'm just hoping for a way to verify that the Mac is actually doing this (using the dongle, not the internal bluetooth). Is there a way to determine that?

Mac Pro USB ports constantly losing power!

Hi,
Ive been looking through this forums but I havent been able to find a solution to my problem.
Ive got a 2008 Mac Pro and recently Ive been experiencing some issues with its USB ports.
The front usb ports have a USB antenna connected and some time later, it just loses power and I have to disconnect it and connect it in order to make it work again. Besides that, Ive got a USB hub connected in one of the back ports. In it, is my camera and my keyboard. After some time, it just loses power. Not at the same time than the usb antenna, but in less that an hour I have to repeat the process 2-3 times.
Worth to note, that in the two back usb ports left, Ive got an external hard drive in each and I dont have problems, there are always seen in the finder.
Some help would be great
Thanks in advance

Im running latest snow leopard.
I gave up and just used a cable for internet and a bluetooth keyboard.
I couldnt figure out why the usb antenna loses power. Though it still has a blue light linking.
What has been happening to you???

Mac Pro USB 3.0

Ordered an Allegro USB 3.0 PCIE card for my mid-2010 Hexacore Mac Pro. Installed and recognized by System scanner, but downloaded drivers don't seem to work with OS X 10.7.3, even though they SAY they are compatible with Lion.
Anyone here have success with this card and drivers under latest Lion iteration? I'm trying to use the ports for my USB 3.0 CF/SDXC card reader from Hoodman. I tried drivers from LaCie as suggested in an earlier thread. Driver is recognized by system kernel panics when trying to use port. At least LaCie provides an Uninstaller.
Other suggestions or is this card a waste of time and money?
mrf

I don't have Snow Leopard to install. I did try booting in 32 bit mode by holding down the 3&2 keys at boot. Because I have some 64 bit kernel extensions installed to support some software, the result was a kernel panic and inability to boot into 32 bit mode.
As for the Sonnet information, I already had that and I have the updated card USB3M-E purchased directly from Macsales (aka OWC) last week. I downloaded the driver you refer to in your post and it simply does nothing. I suppose it is possible that the Hoodman USB 3.0 RAW Steel card reader is one of ones not compatible. Unfortunately, I don't have any other USB 3 devices to test. I did order a supported Lexar USB 3 reader as a backup for another computer.
I might have to install the Windows driver for my Windows 7 - 64 bit VM just to see if the issue is 64 bits or a faulty driver. I'm part of the Mac Developer Program and so I do get early access to certain OS updates. I've been running 10.7.3 for awhile, but when the release version came out, I did the Combo Upgrade to make certain everything was identical to the shipping version.
At this point, I guess I'm going to have to wait for my inquiry to Sonnet and to OWC to be answered, hopefully tomorrow. I did ask whether the card was supposed to support 64 bit OS. It seems to me that if it is Lion compatible that it should be 64 bit out of the box. I also asked whether the Hoodman reader was supported, since the FAQs list Transcend readers as NOT supported, I suppose it could be just reader incompatibility. However, when I look at About This Mac, it shows a USB 3.0 card in the PCI listing, but definitely lists NO driver. When I installed the LaCie driver, it definitely showed YES to driver, but unfortunately the system didn't like the combination.
Thanks for your assistance. It looks like I'm just going to have to wait.

Mac Pro screen issue

Hi all,
my mac pro shows the apple logo at start up and the users available.
Then, either the screen goes crazy with lots of moving thin grey lines or I get to
login in under my account and then the finder has lots of artifacting on the screen
- black blocks in the finder window or parts of top bar displays overlapping text. I've
had some odd black triangle across some of the finder windows too.
If I log in to the guest user (safari only mode) the screen is fine.
Is this a graphics card issue or something else?
p.s. I have tried installing 10.8 but alas, my mac is just one model out from being suported.
Cheers,

Mac Pro USB Failure.

Hello people!
Several months ago, i started to notice some problems with USB devices and built-in USB Ports. The problem is started with these symptomes:
After some working, all USB internal USB ports stop to giving power to usb devices. Only works that had power from another powered hubs like in my Apple Cinema Display.
It can causes at any time, but more expectedly at adding some USB devices (nevermind what, even flash card) to built-in ports of a Mac Pro.
And here is the logs:

But today this problem fully transform to another way. Now, USB devices are all works normal during work in OS which is Mac OS X 10.7.2 Server. But before it, OS booted two times. First time is a Cold Start, which is loooong and sloow. Especially, my OS booted from a RAID-0 of a two SSD drives (during normal start it takes 2 seconds to boot). Then still during boot procces, all USB devices turned off, and Mac Pro self-rebooted automatically. Second time he booted is normal fast startup without a problem.
These i found using dmesg:

Tried to do some testing. Booting to my second OS (Mac OS X 10.4.11 Server) makes the same effect during cold start. And what strange, in boot logs didn't any mention about what causes to reboot. It also does this double boot even if i turn out all USB devices from ports. Resetting SMC and PRAM, clearing and rebuilding Kernel Cache does nothing. Reported to Appel Bug reports... Can't understand what happens, and what to do... Everything was good before the 10.6.7 update. And it get much worse in Lion.

Hello!
I would start by checking which hub is pointed by the mentionned address (0xfd300000).
Do you have Apple Developer Tools installed? If yes, open “IORegistryExplorer” or “USB Prober” and check which hub is referenced. Then, you could start inspecting its properties.
If you don't have them… well, install them
