Internal USB hub causing hang-ups?

Hi, firstly I am running on a 2.16 20" (white) iMac, Leopard 10.5.4.
My issue is that my startup time is tending to grow - not entirely unusual, but while checking the console, I noticed this particular error which itself was adding 10 seconds to launch...
"8/12/08 11:08:35 AM kernel USBF: 12.253 AppleUSBHubPort: Port 1 of Hub at 0x7d000000 about to terminate a busy device (IOUSBCompositeDevice) after waiting 10 seconds"
So I decided to investigate, and I discovered that the internal USB bus, which hosts the bluetooth and IR reciever, has Bus Number 0x7d. Bluetooth is also presumably port 1.

Does this mean I have a problem with my bluetooth reciever? Or could there be something else causing this issue?
A few more errors that are confusing...
"8/12/08 11:09:25 AM /System/Library/CoreServices/SystemUIServer.app/Contents/MacOS/SystemUIServer[1 14] CPSGetProcessInfo(): This call is deprecated and should not be called anymore. "
"8/12/08 11:09:25 AM /System/Library/CoreServices/SystemUIServer.app/Contents/MacOS/SystemUIServer[1 14] CPSPBGetProcessInfo(): This call is deprecated and should not be called anymore. "
"8/12/08 11:09:48 AM mdworker[88] (Error) SyncInfo: Boot-cache avoidance timed out! " - repeated once
The above 3 messages were all in sequence, you can see that there is a 23 second gap between the 2nd and 3rd. Do these messages mean anything to anyone?
If I could resolve these two sets of errors it would shave more than 30sec off of my boot time, which would be very nice! Any help is greatly appreciated.
Thanks!

The problem caused by USB to serial converter comports jumping around all the time is a pain. But it is related to the OS, not to Labview. The only solution I have is to label each USB to serial converter so it end up in the same USB port all the time
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

MacBook Pro (mid-2010) Internal USB HUB freezes/locks up

MacBook Pro (mid-2010) wilth the latest firmware, etc.
OS X 10.9.1
USB KVM to share keyboard and mouse with another computer
This has been working flawlessly until I upgraded to 10.9.1
The KVM uses the Scroll Lock key to toggle the input between the two computers
I switch back and forth many times a day.
Almost once a day now, all my input to my MBP will lock up when switching the KVM over.
The MBP track pad, keyboard, blue tooth Magic Mouse, KVM mouse and keyboard all become unresponsive.
I am assuming that the interal keyboard/track pad/blue tooth transceiver are all tied to an internal USB HUB.
The MBP is up and running and I can ssh into it. The only error message in the log is that the mouse device coming from the KVM is busy and it will be disabled. I have tried to close the lid for several minutes and then re-open, but it does not resolve the issue. I have tried connecting another USB mouse/keyboard during this time and it will not work. I have tried kill -HUP on the usbd and USBAgent processes. Everything stays unresponsive. The only way to resolve this condition is to reboot the MBP. Note: the KVM works find on the other computer when I switch it back and forth regardless of the state of the MBP.
I am suspecting that when this happens it is some how disabling the internal USB HUB, which if all the other devices are connected through it, nothing no longer works (but maybe I am crazy with that thought). Anyone have any insight? Is there a way to reset the internal HUB short of a reboot?
Thanks in advance!

I'm seeing the same problem with a 2010 Mac Mini with IOGear KVM and MS wireless mouse. This setup worked flawlessly for years on Snow Leopard but started hanging soon after the Mavericks upgrade. I'm running 10.9.4, currently the latest release. The system usually hangs after a KVM keyboard switch from Windows on the other set of KVM cables back to the Mac Mini. ssh into OSX works fine but a shutdown hangs indefinitely. top showed no processes spinning. The 1st console message after the hang was:
8/6/14 8:49:21.000 PM kernel[0] USBF: 1317978.201 AppleUSBHubPort: Port 2 of Hub at 0x6200000 about to terminate a busy device (Microsoft® 2.4GHz Transceiver v7.0) after waiting 10 seconds
There were no other messages for hours before this. I'm using VM Fusion but I think it hung once without it running. The Windows 7 side of the KVM works fine.

USB Hub causes Boot Up to hang...

Hey all, I'm a newbie to this site and also to the world of Mac, I recently purchased a New iMac and its fantastic! Now I have a slight issue, I added a USB hub to the Mac and it works fine, all devices that are connected work with no issues what so ever, but when I turn off the Mac and reboot it, it hangs on the white screen, no Apple logo or the spinning loading wheel, that is until I unplug the USB hub and it boots right up!.. I have found also which is interesting, that if my iPod is not docked, the Mac boots up with no problems, so it seems like a conflict between the iPod and the Hub? Does this sound logical and is it also fixable? otherwise I just have to revert to unplugging my Hub everytime I boot up my Mac? Cheers guys, I hope you can help..
Darren

Hi, I tried what you said, but the Mac wont boot whether the iPod is docked or not, the only way it works now is to totally unplug my USB hub wait for it to boot up and plug it back in again? Maybe a dodgy hub? or is there another reason/ solution?
Cheers

Fixing internal usb hub/bus in Dual17"2.4GHz

Hi fellows
my Dual 2.4 17" just fellt to concrete floor and has two mayor problems nom
1) the edge, where de CD/DVD Device is palced is crusehd in really ugly, nad the device doesnt respond at all.
2) more seriouesly i think my USB hub went loose aswell, cause i can start up the machine (therefore considering the DPU, most of the motherboarda as well as the screen to work fine. Even ten nerfing beep comes as expected) But what i cant is, i can use any of the following: Trackpad, Keyboart (all keys), external mours on all 3 USB slots. Therefore i allocate the faualt near the built-in USB hub. Am i wrong? if not so, can somebody post me a link how to get there and fix it?
regards Dhura

Hehe, no ideas worldwide got that tho. Ill just order a new one

USB hub causes hibernation

Hey guys!
I just got a cheap USB hub, and when I connect it to my Macbook, it prevents the computer from normally going to sleep. It results in an hibernation instead of a normal sleep.

Is there anything wrong?

Hi there. The best advice i can give is to invest in the best quality hub that you can afford. The problem in my case was the my wireless modem kept cutting out and the hub getting VERY warm!, now have another one (4 port) with its own power supply which has been going about 15 months and no problems so hope that helps.

Calendar Agent keeps crashing every minute causing hang ups (Beachballs)

Hi All-
Config:
MacBook Pro 8,2 (early 2011)
8Gb RAM/ 1Tb SSD/ 10.10.2/ 1000BaseT ethernet (to cable modem with speeds > 8Mbps to dslreports.com)
This machine was a dog with its OEM 750Gb HD so I replaced it with an 850 EVO 1Tb. And now despite Yosemite, it screams..well for a week or two it did...
Despite the new install (but I did - probably mistakenly - use my Time Machine back up to reload our user accounts) of Yosemite (yuck). While the machine is now moving at about 10x faster than its prior incarnation (before SSD upgrade), I noticed that Calendar kept hanging and causing the machine to slow down only days after this new install.
I included the ever repeating console messages below with the crash and its craziness below.
I am going now to rip out all my calendar preferences on this account and caches and see if that helps, but this is kinda nuts.
If anyone has any ideas, let me know please!
Thanks!
Yosemite is killing me:

I solved my problem for now (see bellow).
I think its not some users problem. If its happening to some users (we dont know how many read but dont write in this discussion groups, we are the visible part of the iceberg!). This kind of stuff shouldnt happen. If its happening than its a bug, and is also happening to me.
I have one ipad2 and one iphone4, and having same problems with icloud.
Cant use email and contacts after icloud and cant also turn them off in icloud.
see the emails "loading" forever and the contacts and bookmarks "turning off" all night long and nothing happening.
Found this in another site that helped me, but I think I will keep email and contacts off, out of the icloud, until I understand what is going on.
I just had the same problem . I went onto my iPad and iPhone 4(updated to ios5),
Go to settings
Select iCloud
Delete account
You can choose to save or delete contacts, calendars and reminders
Reboot your device
Then add iCloud account by following steps 1-3 then use your apple ID and password to set up
Turn everything in iCloud back on. In a few moments, you should be up and running
I turned the email and contacts off (this time I was abble to do it) and now my old emails (gmail) and contacts are working.

IMac 2012 OS's not loading while USB-Hub pugged in. Why?

So i have a problem. I have a new iMac 21,5. I plugged in my iMac through my Smart-UPS and It has an USB control. SO i turn to iMac USB-Hub with 3 USB and card reader in it and to this USB-Hub i have connect USB cable going from Smart-UPS.
When i turning on my iMac its stop loading and i see white screen which goes before screen with Apple logo. As soon as i remove USB cable USB-Hub from iMac its going loading good and then i connect USB-Hub again and it works well. Why it can happen?

ok just did it.
So right now all USB prots on iMac are busy.
- USB Wacom Wirless connection kit
- USB-Hub with cardreader
- UPS directly to iMac
- Wacom tablet.
Turn on iMac and system starting and loading quick
SO looks like trouble was that i had connect UPS through the USB-Hub? Why it could be? Just early when i have this connection of UPS through USB-Hub i notfied that in task bar(or how it called on iMac where clock, menu at the top) there are icon with power pluged to UPS showinig percentage of battery loaded. And sometime its appear and then disappear and jumping here and there. Now when it connected directly i see this icons always appeared.
So it looks like it lost connection sometime and this USB-Hub only for turning usb flash, some low power stuff and memry sticks only?

Using the integrated USB hub on my Thunderbolt Display causes troubles

I just purchased a MacBook Air and a Thunderbolt Display. Unfortunately, when I connect USB plugs to the Displays buildin USB hub, I'm getting severed connections all the time (USB-Connection lost, Firewire-Connection lost, Ethernet-Connection lost...).
I really loved the idea of not having to use external USB-hubs as this only clutters my desk - but the Displays internal hub cannot be used savely (I have a couple of hard drives connected via FW and USB to the Display - this has already resulted in data loss (fortunately I had a backup).
As soon as I'm NOT using the Display's USB ports everything is fine (the Display's FireWire and Ethernet ports do not seem to cause any trouble).
Anyone else seeing this?

Plugging an additional USB hub into the integrated USB hub extends the problematic behavior even further.
If I eject a thumb drive from a USB hub that's attached to the Thunderbolt display hub (for example), it will never recognize that thumb drive again, on any of the USB ports on the display or any additional hub connected to the display, until I reboot with no added USB hub, and then reconnect an empty hub, and then add devices one at a time.
I've also noticed that while some devices drop off, some continue to show up in the system report, even when they have been properly ejected or disconnected. Refreshing the system report doesn't update with what's really going on...
Weird... So since mountain lion, I don't disconnect any USB devices from the Thunderbolt display, unless I really, truly must.

Generic USB hub missing which causes Moble broadband, bluetooth, camera... not working

I've found myself in a bit of a problem.
My W510 no longer have any devices for the fingerprint reader, bluetooth, mobile broadband, integrated camera (and possibly some more).
When comparing the devices in "Device Manager" to another W510, I notice that many of the missing devices are USB devices, but also that the other machine have two "Generic USB hub" and I have two "Unknown device".
When I compare the two hubs and the two unknown devices, they have the same "Location" (i.e. Port_#0001.Hub_#0001 and Port_#0001.Hub_#0002) and I guess that the missing devices (bluetooth...) are "connected" to thoose Generic USB hubs.
If I delete (uninstall) the "Unknown device" from Device Manager and reboot, I can see that Windows detects my mobile broadband device, but during the driver installation they get "device unplugged" when the driver installation for the "Unknown devices" finish.
I've tried to update the driver, but I can't find any driver for "Generic USB hub"
Anyone have a solution to this problem? I really don't want to reinstall Windows, but I might have to do it unless I find a solution to this problem...

Found the cause of the "Generic USB hub" problem in C:\Windows\INF\setupapi.dev.log.
In that file it's clear that the problem stems from the fact that usb.inf is missing...
Now I've got to figure out how to get a working usb.inf without reinstalling the whole OS

K8N SLI Platinum - lockup at boot, caused by USB hub?

Hi.
Updated my bios today as well as enabled 'Cool 'n Quiet'. This caused lockups in Win XP, forcing me to hit the reset button.
After the second reboot the computer refused to boot. According to the D-bracket it stopped at 'BIOS Sign On'.
I followed the troubleshooting guide and ended up here: https://forum-en.msi.com/index.php?topic=75712.msg533104#msg533104
Although the steps taken in the thread above didn't help, one poster mentioned that removing all USB devices could help.
My keyboard is connected to a USB hub in my monitor, when I removed this the comp started up fine, as well as when connecting the keyboard directly to the computer.
Just wanted to pass on my experiences, maybe can help somebody down the line.
Best regards

hi nullmind,
have been 1 or 2 pps had problems with usb hubs, Glad u got sorted will add a link to this thread.
cheers.

Midi and USB hub on new MINI causes kernal panics.

I purchased the lozenge shaped Belkin 4-port powered USB2.0 hub from the apple store yesterday. I had two midi interfaces plugged into it. As soon as MIDI hits it (from Logic Pro 7) the Mini has a Kernel Panic that requires a power cycle. Using the devices plugged directly into the MINI works fine.
Any other experience similar situations?
Thanks
Chris

Hi Chris,
Does the USB hub come with a power adapter?Some midi interfaces need the 5 volts from the usb bus in order to work properly(I have an edirol that only works this way,unless I power it with it's own power supply).

XP Shutdown hangs when USB hub attached :(

I recently bought a Lenovo 3000 N500 notebook (running XP) , and love it. One slight problem though, I have a Belkin F5U271 USB Hub plugged into it all the time, on my desk, and everytime I shut down with it attached, I get as far as 'Windows is shutting Down...' and it just stays there, the fans stop, theres no hdd activity, and it doesnt happen if the hub is detached. I'm assuming its to do with phantom power through the USB, but any thoughts you guys?

I have the same problem when I leave my expresscard34 multimedia reader in the expresscard34 slot in my T400s with XP SP3.
please advise.

Unresponsive keyboard/trackpad and intermittent Bluetooth on MacBook...possible internal USB problem?

I have a mid-2010 polycarbonate/white MacBook (model A1342) running OS X 10.6.8. My machine has been having issues with the internal Bluetooth and keyboard/trackpad randomly ceasing to function.
Bluetooth issue
As of recently (the past month or two), the Bluetooth adapter will completely disappear and eventually reappear on a random basis. It won't appear at all in System Profiler, and the BT menu says "not available". Also, I have had a few kernel panics recently, all of which were apparently thrown by a Bluetooth process/daemon/driver (unfortunately I forgot which one, and also lost the logs from the panics.)
My system has a Broadcom Bluetooth chip that's part of the AirPort card, but is basically just an internal USB device. The adapter has some sort of integrated USB hub ("BRCM2070 Hub"), which the "Bluetooth Module" device itself is connected to.
Nonetheless, this seems to be some sort of problem on the USB bus. Whenever there is a failure, I will almost always see output in Console showing USB errors (ie errors about "enumerating a USB device", "clearing port power", "setting port power", "getting port status", etc). It will either be on any of the ports of the hub at 0x6600000 (the "BRCM2070 Hub" that "Bluetooth Module" is connected to), or port 6 of the hub at 0x6000000 (BRCM2070's port on the internal bus, which the keyboard/trackpad is also connected to on port 3).
I can post more/longer ones, but here's a somewhat short example of the error messages I might receive:
11/18/12 3:18:36 PM kernel USBF: 7351.492 [0xcf9b300] The IOUSBFamily is having trouble enumerating a USB device that has been plugged in. It will keep retrying. (Port 6 of Hub at 0x6000000)

11/18/12 3:20:20 PM kernel USBF: 7456.188 [0x11fb1300] The IOUSBFamily was not able to enumerate a device.
Keyboard/trackpad issue
There's also an issue where the internal keyboard/trackpad will randomly cease functioning (until I restart), often a couple of times a day as of recently. I've had this issue on rare occasion for a while now, but it's gotten more frequent. And more recently, the caps lock light on the keyboard occasionally turns itself on when I'm away.
Both the internal keyboard/trackpad as well as the Bluetooth "hub"/device are connected to the same USB bus/hub. When the keyboard/trackpad die, I've noticed that there will be very similar messages in Console to those above and usually a Bluetooth failure at the same time. (In some cases, it seems to notice that the keyboard/trackpad isn't responding, then attempts to reset/reinitialize it...ie log below.) What could the root cause be...could it be the USB "root" hub/bus causing one or both of these to fail, or possibly a problematic device causing the other to lose connection? I haven't had issues with USB devices on other buses failing, though (ie no problems with external devices.)
Maybe more out of curiosity than anything else, but I've been poking around for info on what might be going on with the USB (aside from the 0x66 hub repeatedly dropping/reconnecting and etc), but can't find much. There seems to be no documentation about the error codes (ie 0xe00002c7) that the hardware/OS are relaying. I even poked through the source for some of the relevant kexts and some reading on OS X driver/kernel programming too...might as well learn more about the inner workings of OS X
Here's an example of some of the messages that I get about the Keyboard/Trackpad:
11/21/12 2:57:22 AM kernel USBF: 1439.228 IOUSBHIDDriver(AppleUSBMultitouchDriver)[0xd1ff000]: Detected an kIONotResponding error but still connected. Resetting port

Attempted fixes
Unfortunately, my Macbook isn't under warranty so I'm mostly on my own. First I zapped PRAM, reset SMC, ensured OS updates are installed (still on 10.6.8), and threw out a few drivers/software that were possible troublemakers. Next, I tried running another OS/install to rule out software issues. Accordingly, I found that the BT adapter sometimes disappears on Windows 7 as well (just did a clean install). And finally, I bought a new AirPort/BT card and installed it the other day. That seemed better at first, but I still have the problem of intermittent Bluetooth and keyboard/trackpad.
Problems/solutions?
What might the issue be, or is there anything that may be worth trying? As I mentioned, I've reset PRAM and SMC, made sure it's not an OS/driver issue (it happens on Win7 too), and replaced the Airport card. The machine does have aftermarket RAM (from OWC, ~2 years old) and SSD (Crucial M4, installed September)...but it seems unlikely that either of these would cause the problem. There haven't been any accidents that would have caused physical or (to my knowledge) electrical damage to it.
I also searched for any occurrences of similar problems, but could not find any that were applicable to the Macbook revision in question. There was a similar keyboard/trackpad issue on older Macbook Pros that was caused by stress on a ribbon cable...but that seems unlikely given the concurrent issues with Bluetooth as well as the different design.
The only thing I can think of next is to possibly replace the cable connecting the Airport card to the logic board, and possibly look at replacing the keyboard/trackpad (topcase). Anyway, I'm worried that it might be a hardware issue with the internal USB controller/hub, which would probably mean that it's unfixable unless I replace the logic board.
Any advice as to which of these might be a potential solution or cause of the problem? Or might I just as well sell it off in its current condition and replace it?
Thanks all!

Has anyone find a fix for this? I've been using my Dragon Dictate headset on my MacBook Pro for about a year, and then today, when I plugged it in, I got this:
4/16/14 10:01:04.000 AM kernel[0]: USBF:    47.766    The IOUSBFamily is having trouble enumerating a USB device that has been plugged in. It will keep retrying. (Port 1 of Hub at 0x4000000)
4/16/14 10:01:07.000 AM kernel[0]: USBF:    50.269    AppleUSBHubPort::FatalError - Port 1 of Hub at 0x4000000 reported error 0xe00002c7 while doing clearing port power feature
4/16/14 10:01:07.000 AM kernel[0]: USBF:    50.269    The IOUSBFamily was not able to enumerate a device.
Here is what I have tried so far:
Reset the PRAM
Reset SMC
Verify disk (there were no problems)
Repair permissions
Boot with an external USB hard drive (which works fine on the "problem" computer) that contained an old SuperDuper clone of my hard drive from several months ago. I received the same "The IOUSBFamily was not able to enumerate a device" error when I plug in the headset.
Tried to headset on another computer, and it worked fine.
Plug in an external USB keyboard into the problem computer, and it works fine.
All of this would lead me to conclude that it is a hardware problem. But it seems that if it were a hardware problem, the external USB keyboard and external USB hard drive would not work (which they do). If the problem were with the headset, it wouldn't work on another computer, but it does. So I'm wondering if it's some sort of firmware issue…??????? URG!!!!!!

External Firewire HDD causes hangs on my Mac Pro & HDD lag using finder

External Firewire HDD causes hangs on my Mac Pro & HDD lag using finder.
I have an 2008 Mac Pro 8 core 2.66hz, 10GB Mem, ATI HD4870 with 4 internal 1 TB Drives. I have 3 external HDDs (2 USB + 1 FW400). The 2 USB HDDs are for Time Machine and backups.
The external FW HD is a 1TB bootable clone of my Internal 1 TB boot HDD.
I have 2 problems ... somethimes when using finder or opening a folder, copying files, starting or quiting a program, I get the spinning beach ball that seems to hang the Mac.
I power off the external FW HDD and everything starts to work. I get an error about the device going offline, I then power the FW HDD back on and all is good.
It seems the external FW Drive tends to hang the system. It occurs pretty frequently.
Any recommendations?
The other issue is that when I use finder to go to a folder, I seem to have to wait for all these drive to spin up. You can hear them all start whirring.
is there a way to remove that lag?

If you recently moved to Snow Leopard you might look for new firmware for your external drive. I would also get DiskWarrior and run that on the external and consider programs like Drive Genius. You might also back it up and wipe it and restore the data. After that I'd consider looking at a new external.
Sleeping drives that take time to spin up after waking....I'd like to learn how to stop that myself. Be sure the Energy Saver in System Preferences is set to not put drives to sleep when possible. Even then my drives will go to sleep and I have up to 6 external added at times and they take quite a while to all spin up. I've never found a way to prevent that.
BTW...external USB drives on a MacPro? Really? Even for backup....

USB hub stopped working

For years, I've used a powered Belkin 6-port hub to connect an Apple aluminum extended keyboard to a rear port on a 2008 Mac Pro: the way my desk is laid out, the pathetic 3 foot keyboard cord otherwise doesn't reach. A couple months ago, upon restarting, the keyboard wasn't working, so I had to plug it directly into the Mac to start up, but once it was running, could switch back to the hub and it would work fine. Now the keyboard is only working plugged directly into the Mac. I haven't changed operating system or internal hardware during this time. I tried a Belkin USB extension cord, but the Mac acts as though nothing is plugged in.
Is there either an extension cord or USB hub that will more reliably work between a keyboard and Mac Pro? Thanks.

Amazing! glad got it fixed. Thought you were going to have to buy another kb (Amazon has those too and some of the older ones I like better, free s/h and no tax).
A couple people found the Apple USB Extension we all got to be an issue. For me, crimp where the mouse cab le was ''bent' and cause some kind of short.
