X40 USB failure

Hi All,
I have an X40 and running Win-7 all worked fine until recently I removed a USB device (IPhone-4) from the right hand USB port the computer rebooted itself and since then I have no USBs available.
If I insert a memory stick into the X40 I get a red light on the stick but does not access the data, if I insert a memory stick into the USB ports of the docking station I get no red light or data access, this may be unrelated but the docking station USB's did work before.
Can anyone offer some advice.

I have an x40 board here in a box that does the same thing. x40's were suseptible to having the ports fail. It seems to happen more on the older x40's, the ones with the 1.2 and 1.4 processors, but it does happen on the 1.5's also.
Sometimes, what would happen is the piece of plastic that covers the contacts comes off with the cord and the next time somebody plugs something in it fails. Other times it just quits. Right now, it sounds like yours can see things, but can't power them.
It's said to be related to the southbridge problem with the t4x series. I've only ever had one fail out of about 5 x40's and that was with the 1.2 processor. The only fix is to replace the board.
If you boot up with a linux distro, the ports might work with 1.1. They just won't work with windows. That's not set in stone, though.

USB failure on MSI K8N Neo2 Platinum

I have 4 USB ports on the back of my MOBO. I connected my Sennheiser USB headphones for the first time and the USB was found and installed in XP SP2. I got sound. I took them out. The next time started my PC and plugged in the USB there was no search for USB and also I had no sounds in the headphones. In the devicemanager however, the USB popped up as "USB-device compound" and also in devicemanager sound-, video- and gamedevice there was a "USB-device" popup.
I tried with the same thing with all ports and samething happend when I restarted my computer = no sound.
This is not just for the headphones I noticed for other USB devices too.
The only thing I have tried to do is to delete the USB-devices, I could delete all besides "Standard Enhanced PCI to USB Host Controller". When I deleted that I had a bluescreen failure.
Note that I have my mouse connected to my USB.

nicoliani,
Sometimes USB Headsets can be funny. They will at times mess with the Audio on notebooks too. I have seen cases where after removing a USB Headset from a notebook cause the audio to completely go on a notebook (Several different notebooks which were different brands and chipsets along with completely different USB Headsets.) and even with the Audio Panel set correctly, not get sound. Even after serveral reboots, the sound did not return. After after several more reboots, the sound finally returned to the notebooks. Go figure.
As for your situation. When you go in, the device manager make sure you delete all USB Devices and let Windows find them again. (Make sure you have your Keyboard and Mouse connected to the PS2 Port for this and disconnect all other USB Devices.)
Also when you use the USB Headset, make sure to go into the Audio Settings and have the proper devices selected as default.
Take Care,
Richard

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:
Dec 30 18:53:24 Viktors-Mac-Pro kernel[0]: 0            0 AppleUSBCDC: start - initDevice failed

Dec 30 19:10:01 Viktors-Mac-Pro kernel[0]: USBF: 1148.583 [0xd45b700] The IOUSBFamily was not able to enumerate a device.
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:
[KLogClient]start(0x12a26f80)

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.
mac: Mac Pro 2,1 (2007)

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

Get a little USB in my life - classic BB USB failures?

Being the owner of a second hand PB that arrived without a working micro usb port, I am constantly curious how it feels to have use of it. We get by just great otherwise.
The hdmi port has also tested broke, dysfunctional.
Several lead tests, and config checks have proven unsuccessful. So, somehow, they is busted.
SO, I wanted to ask about
--- the durability of the BB ports. What could do that? A drop, a knife in the slot? Are failing ports common. Somehow I doubt it.
--- the cost of renewing the ports. Seems silly as it works brilliantly without them. I am curious to see how it would work in the schools I work in through hdmi tv, for sure.
--- how many PB owners own TWO? It would be understandable, of course..!
Any info on experiences of causes, costs to fix much appreciated.

my kids would rip out the charge cord, try to connect to teh HDMI port to charge and broke 3 USB chargers.
I now have magnetic chargers and teach them how to connect the HDMI to the TV. they have had playbooks since June 2011 and after a few scares they treat them much better now that they are 8.

2011 Macbook Pro Usb failure

My brand new (week old) MBP has trouble recognizing my external hard drive and/or usb jump drives. The external drive (which is powered by an adapter) is recognized after wiggling the connection in a specific way, but no such luck with one of my usb jump drives.
I can eventually get some of the drives to show up in Finder, but it's very inconsistent. Is there anything that I can do myself at home short of booking time at the Genius Bar?
I've read the posts regarding this issue that has been common over the past couple years, but this is a BRAND NEW Macbook Pro.
Thanks,
Jay

You probably need to go ahead and book a visit at the genius bar and find out what is wrong with your port. It sounds like the port may have a loose connection, and if so, that is a hardware problem that needs to be addressed. It is of course covered by your warranty.

Boot from windows 7 usb failure

Hello,
I'm trying to install windows 7 on my 15" mbp running OSX lion.
It's a end 2011 series.
I have a working bootable USB created with the "windows 7 usb dvd tool"
I'm pretty sure it works because i'm able to boot from it on my windows xp pc.
Using bootcamp, i made a 75Gb windows partition,
but wen the mbp restarts after making the partition i only get a black screen saying
"no bootable device insert boot disk and press any key"
I've tried taking the usb out, and putting it back in, no succes.
I've hit every key on my keyboard, no succes.
Also, I can't use the usb as a start up disk, because it isn't in the list (in the preferance panel)
I hope someone can help me with my problem.
Funny how the only trouble i've had with mac in 8 years, is installing windows.
Thanks,
Louis

Not sure what you are doing wrong but I and many others have done this without any problems. In fact installing Windows is almost a prerequisite if you are going to have a Mac as your main and or only computer.
Try deleting that partition, using Boot Camp Assistant, and try doing it again. Make sure the Win 7 USB stick is in a USB port.
Not sure but I might remember that I needed to use the DVD drive to install Windows. The Mac just wouldn't look to the USB ports for any bootable device once boot camp rebooted the system.

USB failure: "The project appears to be damaged, it cannot be opened." CS2

First of all - yes, I'm using CS2. I can't afford to buy a newer version at the moment, so I'm living in the past.
Second of all -- I am committing several egregious sins that would make my past video editing teachers cringe: I was editing directly off my USB, and I didn't make the occasional iterated file-name save as I ought to have. I realize this is rather poor planning on my part, but my lack of harddrive space (and USB disk space, honestly) dictated my actions more than my better judgement.
After saving a file -- not experiencing any crashes, mind you -- I went to edit one of the unrelated clips in After Effects to import into Premiere, because I had a few fancier things I'd wanted to do before importing it. Upon finishing the clip to my satisfaction and exporting it, I returned to my Premiere Pro project, only to be greeted with the following error:
"The project appears to be damaged, it cannot be opened."
So, into the wonderful world of autosaves I go (because there is only so much advice I can stand to ignore, and the autosaves are one feature I turn off only when absolutely positively desperate) -- except the autosaves all appear to be similarly affected, much to my dismay.
Advice? Is my work unrecoverable? Is it a matter of looking for USB repair software? Is there some trick I can employ to let it load whatever parts are not corrupted, and fix whatever is? The file certainly seems large enough to contain at least some useful information, though I know that means almost nothing in the world of oh-my-gosh-what-did-I-just-do-fix-this-ack-is-this-the-end-etc-etc computer errors.

OK I've tried to make sense of this an to troubleshoot it myself. I've spent lots of time trying to find a solution relevant to the problem, but so far have not. Seems time to submit and see what help there may be.
I'm using Premiere Pro 3 on a HP desktop with 3.0 GHz chip, w 4 GB sys memory using MS WinXP. It's sold as a "media PC".
There's a 2TB WD MyBook external drive attached by fire wire to the desktop PC (PC A). The desktop PC has 150GB hard drive and a high end graphics card that supports dual monitors. I've been editing with this rig over 2 years with no problem.
I have various other external hard drives I've been using with no problem, including another MyBook 2TB, an Iomega 500GB, and 3 or 4 small WD Passport type hard drives with 400GB to 500GB apiece. I have two laptops that meet the system requirements for using Adobe Premiere Pro CS3. Both have PPro CS 3 installed.
Recently, I started getting a message when opening PPro projects on this drive using the desktop PC: "project appears to be damaged, it cannot be opened".
In the past, this message has happened occassionally. When it did, I'd retrieve a file from the Premiere Auto save directory and just continue on with no problem. More recently - this past weekend - I suddenly found all the PPro projects on the 2TB external drive generate the same "project damaged" message when I try to open them.
I have various PPro projects in progress on other external drives used on other PC's. So I opened PPro project files on another drive with the same desktop PC A with no problem. All projects on other drives open OK on the desktop PC.
So it seems the desktop PC is not causing the "projects damaged" problem.
Then I used a different PC - one of my laptops that has the same PPro software installed - same version installed off the same disc. Using the project files on the 2TB - the drive that seems to generate the "files damaged" messages, has no problem opening on one the laptop PCs. So it appears the 2TB external drive is not source of the problem since it works with PCs besides the desktop.
It would be great to diagnose the problem so I could get a solution, but getting a diagnosis seems to defy logic.
The project files on external 2TB drive - when used with the desktop - don't work
The project files on different external drive, when used with the desktop - work OK
So the desktop is not causing the problem, because PPro project files on other drives work fine on the desktop.
So maybe it's the 2TB drive that's the problem.
The same project files on the 2TB drive - where the "projects damaged" message happens - work OK on either of the two laptop PCs.
The projects on the 2TB drive all open with no problem on the laptop PCs.
Since the project files on drive the 2TB drive work fine on both laptop PC's, the 2TB drive is not the source of the problem either.
Just to be sure, I completely uninstalled the entire Creative CS3 Suite from PC A the desk top and completely reinstalled it.
Same problems, uninstalling and reinstalling the software makes no difference.
o Using PPro project files on the 2TB drive, with the desktop, generates the "projects damaged" message.
o Using PPro project files on the other drives, with the desktop, generates NO "projects damaged" message.
o Using the PPro project files on the 2TB drive with other PCs generates NO "projects damaged" message.
Hope this makes sense. The symptons certainly don't Thanks for whatever advice and feedback can be shared. GWDMRG

IPAD 2: Lock on Apple Startup Logo/USB Failure

I am extremely disappointed in my local (Vancouver, BC, CAN) apple store and really apple corporate. I received an Ipad 2 last year on May 13 for my birthday. One week ago it froze on the apple startup screen. I brought it into the apple store expecting them to fix it or stand behind the product. I was politely informed that there was an error reply on my USB and that I was beyond my warranty, so my options were to buy another Ipad 2 at a lower price or buy a new one. All my apps, movies, music and any other files are gone and my option is to buy another. Talked to tech help, talked to the local manager and same answer and a friendly smile. I have an apple tv, powerbook and ipod and not a problem. I don't know where else to voice a complaint. It is a disheartening end to the business relationship with Apple.
Merle ([email protected])

You're past the end of the warranty yet were still offered a replacement product at a lower cost. What's wrong with that?
You say all of your apps, movies, music and other files are gone?
1. You can redownload all previously purchased apps again at no charge.
2. You did sync with your computer didn't you? Anyone who doesn't have a backup plan for their data is asking for trouble.

USB Failure

I've had USB port trouble even with the installation of a new LogicBoard. When the computer is on and you then plug in the ipod, it will show up on the desktop. Once you restart the computer that particular USB port was rendered useless. It picked up no ipod, no USB MIDI controller, or keyboard or mouse. I took my mac to the apple store to figure what was wrong. The Genius guys verified that there was something wrong with the USB ports and decided to replace the Logic board. Well I got the computer back with a new logic board only to find out, that I still have the same problem. Something is up with my USB ports and don't know how to fix it. Has anyone had similar problems?

Actually I have tried creating a different account and reinstalling the OS. But still no go. I'm thinking it has to be something with the USB drivers.

USB failures

I have had repeated USB problems with my nearly one-year-old MacPro. At first they were intermittent and difficult to reproduce (and an Apple Repair centre couldn't replicate any of them a few month ago) but now they are crippling: the Mac responds to my keyboard most of the time and my tablet pen some of the time and fails to connect to most other USB devices at all.
I have tried various combinations of USB ports, cables and powered hubs to try and eliminate problems with the individual ports or cables. But the problems are consistent whichever means I use to connect to each device and I have also tested as many of the devices as I can with my Mac Book Pro, so I am sure that the problem lies inside the MacPro. How can I check whether it is delivering sufficient power through its USB ports? Is there a way of monitoring USB power levels?
The other relevant information is: I still have one external USB hard disk mounted in addition to the keyboard and tablet but after a restart it may take a couple of minutes to mount. And the Powermac has always been flaky at recognising any other computer attached to a wireless network (through a Netgear modem/router) whereas my laptop can always find the MacPro. Oh, and my tablet pen stopped responding half a dozen times while writing this (each time for about 15 seconds).

I can't answer your question, but I can sympathise with your predicament. I'm having similar issues - all of my USB ports and bluetooth will intermittently stop working. When that happens, I have no keyboard or mouse (or external hard drive).
My MP is in the "shop" right now (for over a week) getting a logic board replacement. I hope that will cure the problem.

Macbook usb failure

on my newly purchased macbook 13.3 inch 2.4ghz. i discovered a newly formed problem. whenever i plug in any usb device my macbook goes all gray and tells me to restart or tun it off. this happens with ipods, cameras, gps,etc. it only doesnt happen with printers. how do i fix his?

Frankly, this sounds more like a software problem than hardware (since you appear to say that your printers work over USB). Have you tried to boot from your install DVD as I suggested yesterday? I'd try to eliminate any software issues before you send your computer off for repair/replacement. Note that Apple's Mac OS X installation DVD can also be used to diagnose problems since it allows you to run your Mac from the "clean" system that resides on the DVD rather than on the possibly corrupted or problematic system that resides on your Mac's hard drive. To start with, you do _not_ need to reinstall the OS when using this DVD (even though it is called the "Mac OS X Install DVD"), you can instead use it to run Apple's Disk Utility to check whether you can access your USB storage devices while running from the DVD. If you can access a USB flash drive or HD while booting from the DVD then you almost certainly have a software issue and not a problem with the hardware.
So, boot from the so-called "Install" DVD and then select your language (I assume English, so select "Use English for the main language") and then when you get to the "Welcome" screen go to the "Utilities" menu and select "Disk Utility...". After that plug in a USB-based storage device (flash drive, "thumb" drive, or HD) and see if you can access the device (if so, it will mount and be visible in the panel on the left side of the Disk Utility window, there you can also run a verify operation on the disk). If this works then you've isolated your problem.
After you've used Disk Utility you just need to quit out of both the utility and the installation program (back to the "Welcome" screen). Then as the DVD exits it will ask you whether to restart or to select a startup disk. You want to select the startup disk so that you can reboot to the OS that is on your HD.
As a "last" shot I'd also reset the MacBook's SMC (System Management Controller). I don't think the SMC has anything to do with USB (directly) but if by some chance that can correct your problem then there is really no harm in trying (since the whole process takes less than a minute). Here is a link to the Apple Support article on resetting the SMC (I believe that on the newest Macs a reset of the SMC will also "zap" or reset the PRAM):
http://support.apple.com/kb/HT1411
In fact, a reset of the SMC is so quick and easy I'd try that before you check your system with the installation DVD (although the latter doesn't take much time either).

Sudden USB Failure

My usb has been working fine for 5 months...even after installing sp2. One day nothing will work (even though I dont believe anything was tamperd with). Everything I plug in is an "Unknown Device"... I have usb 1.1+2.0 enabled in bios... I have also tried clearing the CMOS... still no luck... any other ideas? Thanks for the help
-I have also already removed the extra pin from the front case usb cables (and everything was working fine after that)
-Also tried removing all things in "USB" category and reinstalling...no help...

Instead of reinstalling you could also do system file checker
Windows 2000 & XP comes with a very handy tool called the system file checker. The SFC tool itself will scan your computer for system files that may have been replaced when some old or poorly made program was installed. This usually happens because the programmer who made the software did not create it to check the versions of each system file it replaces.
To protect your computer from old system files, Microsoft created a special service that is built into the operating system. This service monitors your system files, and if one is replaced or deleted, ICS will automatically restore the system file.
SFC works in conjunction with a utility called Windows File Protection that keeps the system file cache: (%Systemroot%\System32\Dllcache) uppdated with the newest Microsoft Approved files as they are installed on your system. I prefer to use the system backup for the ability to roll back to a former configuration however.
To manually invoke the system file checker, be sure you have administrative access then go to the command prompt and type:
sfc /scannow
The system will immediately begin to check all the current system files and restore the cached approved copies. You may be asked to insert the Windows CD as well during the restore.
Clue: Keep in mind that after you perform a system file restore you should install the newest service pack so you are running the most current, Microsoft approved system files.
For you XP users, SFC should be used as a last resort. If you have been creating system restore points, first roll back to your latest restore point and see if that fixes your problem.

Kikusui PLZ334WL Intermitent USB Failure

I am trying to write an automated test program in LabVIEW using a Kikusui PLZ334WL. However, it appears to "drop out" intermittently, causing a Resource Not Found error. The other USB controlled instruments are working fine, and the Kikusui works fine for a while, and then disappears. A power-cycle of the instrument appears to be the only thing that will bring it back...which is of course counter productive for automated testing...
One of the other engineers that I work with says he has seen this in the past when using USB, but not when using serial communication with this instrument.
Has anyone else seen this issue, and have an idea why it may be occuring? I contacted Kikusui, but have not gotten a response yet.

I know this is digging up an old thread, but I'm still dealing with this issue. While most of the intstruments that I am trying to control all work nicely together (regardless of how they are connected to USB) the Kikusui electronic loads do not. These particular instruments get very intermittant during repeated opening and closing of the resource using VISA as I cycle through all of the instruments. They always hang up on the Open command...but not every time...it can happen anywhere from once in 10 loops, to nearly every loop. I always open and close each instrument before moving on to the next instrument, never leaving a resource open.
I have discovered that moving the USB connection around does seem to affect this issue. Just yesterday I discovered that my recent issues were allieviated by moving the Kikusui USB cable from the hub that all the other instruments are connected to, directly to another USB jack on my laptop.
I tried using the USB hub both powered and unpowered with no affect. I now only use USB cables with inductive chokes on each end, in order to reduce common mode noise in the cables. No other instrument has any issue with this setup. Why do these instruments have this issue? Other than connecting to another USB port, is there anything I can do from a software/configuration perspective to improve the robustness of this connection?
Another issue that I have is that I tried setting the VISA timeout to various values from 2000ms to 10000ms, and it doesn't seem to matter. The instrument always times out at exactly 2 minutes when this communication issue occurs. It is good that it eventually times out, but why doesn't the VISA timeout work? I am able to get the connection to reset by unplugging the USB and reinserting it....but unattended, after exactly 2 minutes the instrument will eventually release and allow the code to retry to open the resource. Sometimes it takes 2-3 tries before it is able to actually open, adding considerable time to the automated testing. If I could get the VISA timeout to actually work, I could shrink this 2 minute delay down to a few seconds, which would be nice...but still obviously not fixing the problem...
So, in conclusion, two questions:
1) Is there any way to improve the robustness / reliability of the USB connection to this instrument through some VISA setting or something (regardless of how the instrument is connected)
2) Is there any way to fix the VISA timeout property so that it actually has an effect on timeout?
...for what it's worth, this sounds like a very similar issue:
http://forums.ni.com/t5/Instrument-Control-GPIB-Serial/Intermittent-visa-error-BFFF0011-with-viOpen/...
Referring to message #4, I hate resorting to leaving the resource open for the whole test, but this is the only suggestion that I have seen that seems like may work...

USB Failure after Updates

I see lots of people with USB problems after the latest update, but I have had this problem with every single update apple has released since i bought my powerbook. Rebooting SOMETIMES helps, but generally it clears up on its own. Still, after every update I install I can only use my right side USB port for a few days and it gets very annoying. Anyone come up with more permanent solutions for this problem?

Some have found that resetting the power management unit (PMU) fixes where one side of the USB stops working. Apple note with instructions at http://docs.info.apple.com/article.html?artnum=14449
Also, there have recently been a number of odd issues associated with doing system updates via the software update function. I've started doing combo updates, which is a more thorough, complete system update. Before doing a combo update, I clear the system and kernal caches, using OnyX, although there are other programs that do that too.
