All USB stops working after restarting iMac, please help!

I am having a serious problem with my iMac and i'm at a loss of what to do. I have a 24" imac with 10.5.6 and about a week or two ago I restarted my computer only to find that none of my USB ports were working. I thought it was a fluke so i just restarted again, only to find out that they still wernt working. I was forced to do a restore because I couldn't find a fix so I booted up from my leopard disc and did a restore from my time machine backup. I thought all was well and good until i restarted again yesterday. The same exact thing happened so I did another restore. Well, I just needed to restart my computer again and what do you know, my USB stopped working again! I have repaired permissions, done the apple hardware test, reset the PRAM, and verified the disc to see if there was anything wrong with it. I am at a total loss on what to do and Im really not looking forward to doing another restore only to have it do the exact same thing. Please help!

If you haven't tried this, try resetting the SMC: http://support.apple.com/kb/HT1543?viewlocale=en_US
When you booted from the restore disk, did you run Disk Utility to check the hard disk for errors?
If not... make sure and disconnect anything connected to the USB ports first,
To check the hard disk:
Open Disk Utility, in the Utilities folder in the Applications folder.
Insert your Mac OS X Install disc in your computer’s optical drive or an optical drive connected to your computer, and then restart your computer. When you hear the startup tone, hold down the C key until you see the progress indicator, which looks like a spinning gear.
Follow the onscreen instructions until the Menu Bar appears with the Utilities menu in it, choose Utilities > Disk Utility, click First Aid, and then click the Verify button. If DU reports errors, click Repair. When it's finished, from the Menu Bar, select Utilities/Startup Disk. In the Startup Disk window select MacintoshHD 10.x.x and click Restart.
Also, click the Apple logo top left in your Desktop, click: About This Mac, then click: More Info
That will launch your System Profiler. Under Contents on the left, click: USB and make sure your USB information is there.

Ok actually my mistake it says "an error occurred during activation. try again" I spoke with apple tech support right now and she mentioned they are having trouble with there servers. Do you by any chance know what the restrictions area means? Should that be activated or deactivated, does that make a difference?

Cinema display USB stops working after upgrading to mountain lion

I am using a newly bought 27' Cinema display + mid 2011 MBA. an Apple USB keyboard is attached to the display USB port, and a logitech mouse is attached to the USB port on the keyboard.
After upgrading to mountain lion, when I unplug the thunderbolt from MBA, and then plug it back, the USB keyboard and mouse stops working. Moreover, I cannot open anything in System preference, and cannot properly shutdown the machine!
Please help on this issue.

Launch Terminal, type or copy/paste the following:
killall Dock
Hit enter.

After software update, airport an USB stops working. Clean install fixes it until I update

I've reset PRAM and SMC erased and reinstalled 10.6 multiple times. Everything is fine until I do a software update. I can boot into windows via boot camp and all is well, but in OS X some USB ports stop working, and airport will say no hardware installed. I've repaired permissions as well with no luck. No AppleCare left so I can not call Apple.

I have this problem too. I have the 27-inch LED cinema display connected to my Mac Pro 1,1 via the Radeon 5770. I also suspected it had something to do with the machine going to sleep, but the audio doesn't disappear every time it goes to sleep. Unplugging the monitor fixes the problem.
I also noticed that when the sound has went away, if I try to change the volume there will be a long delay before seeing the volume-change graphic. Also, toggling the sound device in System Preferences while the problem is in effect is unresponsive, sometimes giving the beach ball. Finally, this message is seen in console logs when the sound has went away:
10/19/10 6:01:22 PM kernel USBF: 75053.200 AppleUSBEHCI[0xf3d0800]::Found a transaction which hasn't moved in 5 seconds on bus 0xfd, timing out! (Addr: 5, EP: 0)
I can make this message appear on demand by attempting to change the volume.
If (when) this happens again, I'm calling support.

Satelite Pro S300 - USB stopped working

Hello
I have a 6 months old laptop Sat Pro S300-100 and are running Vista 32-bits. It's got 4 USB slots, 1 combined who is working on left side, and 3 USB2 slots on right side and these 3 suddenly stopped working. I've tried different connections, USB mouse, external disk, memory stick, but they are all dead.
I've tried to deactivited and activited them, no change. I've checked the ports and the system response are that they are working.
I've had a similar problem earlier on a Tecra 9000 some years ago and the replaced the main board.
Does anyone have a solution, please?

Hi!
Do you have yellow marks in the device manager?
I think there is a hardware problem. Contact an ASP (authorized service provider) to repair your notebook.
Here you can search for:

Satellite C655-S5049 USB stopped working

Bought laptop 1.5 mo ago. USB was working but today won't recognize anything plugged into either port. Tried disable/enable USB via HW Setup, no go. Anything else I can try before losing weeks to warranty service?

Alrighty ... my USB stopped working

I have no idea why and not really sure where to start. It always worked, but recently, it just ... stopped. It works in Windows, so it's not the hardware.
So I plug in a USB thumb drive and it displays in /dev as sdb, but doesn't display the partitions. When I do a cfdisk /dev/sdb, it says that the partition table is fubarred. When I plug in an optical mouse, it lights, but it doesn't do anything to the cursor when I move it.
Any ideas?

Well, here I am again blaming myself for blaming linux. I moved my xorg.conf to xorg.conf.test and tried running the server without a config - my USB mouse works. And it turns out that the thumbdrive's partitions were messed up to begin with. The odds pointed at linux, but it was just testing my loyalty
I'll fix my configs and format this drive. Thanks for the support guys!

Helix tablet USB stopped working

The USB port on the tablet portion of my Helix has stopped working. It does not work with any device now. It was intermittant for awhile and then stopped completely.
Uncertain if this is a software issue or hardware and if hardware how does one change the USB port?
I have checked all drives and updates BIOS, etc.

What specific model of L755 do you have? There's a Toshiba label on the bottom of your computer.

Overo, usb stopped working

I'm having a puzzling problem connecting a usb camera to a gumstix overo mounted on a summit breakout board.
In short, I plug in the board, everything looks ok. I try to access the camera (even just v4l2-ctl --list-devices) and /dev/video disappears, and the usb port no longer functions (tested by plugging in a thumb drive that works prior to plugging in the camera). Here is the problem in more detail.
Plugging in the camera I get this from dmesg:
[ 672.371398] usb 1-2: new high-speed USB device number 2 using ehci-omap

dmesg returns:

From this point on, plugging anything into the usb port has no effect. I'm not sure if the usb hub is browning out or what.
Any suggestions on what to try next to debug this? I tried unloading and loading various modules, stopping and starting udev, etc.. to no avail. However, I am a total arch newb so I could have done all of these things wrong.
Thanks in advance for the help.

USB Stops Working, Hardware or Software Issue?

I am having a strange problem with my laptop. It's a Dell Latitude E6410. I noticed this problem for the first time yesterday.
Whenever I'm home, I plug in a USB keyboard, USB mouse, and sometimes my PSP to charge or add files. All of this normally works. Yesterday, I was deleting everything from my PSP hard drive, and in the middle of doing so it just disconnected. I noticed that my USB keyboard and mouse stopped working too, my mouse didn't even have the laser lighting up on the bottom. I restarted and everything was fine.
Last night I put my computer on standby, and just now I woke it back up. Upon doing so, none of my USB devices were functioning again, and I had to restart my laptop and that did fix it.
My confusion is whether this could be a software issue or hardware issue. I've never had an issue like this before. I notice that my mouse doesn't start working and my PSP doesn't start charging until after Arch starts to boot, so I wonder if there is a daemon that might be dying or something?
My laptop is under warranty so if it's a hardware issue I'm covered, though if I call Dell tech support I'll have to put my Windows hard drive in it (which I keep just in case I have to call tech support) but I thought I'd ask here before I go through all that.

Perhaps it is a software issue since it occurs after putting the laptop in standby.
Some BIOS programs have a legacy USB entry. Perhaps that needs attention for whatever reason.
If on internal power, low battery charge could introduce discrepant behavior. This is not likely if on wallwart power.
Review recent upgrades for clues to the solution.
It doesn't happen only after standby. The second time it did, but the first time it happened right in the middle of transferring files from my PSP.

USB stops working

All of a sudden I have the USD on my Mac Pro stop working and then I have to restart. Is there a PRAM battery that might be doing this? My Sound Stick and XKeys are not recognized. Any suggestions?
Thanks
