USB Ports Not Recognizing Thumb Drive

[~zQ~]

Everything with my build has gone relatively without flaw until my back USB ports stopped working. At first my Sandisk Cruzer Mini 1GB USB drive worked without a hitch and could mount and transfer without problem. Then I unmounted it to bring it to another computer, and when I brought it back to this system the system tray had a popup saying this USB device is not recognized and that it malfunctioned. I know its not with the USB drive because it works fine on the other computer. I try different ports and the same error pops up. I then install the newest nForce chipset drivers and everything was fine again...until I tried it again today and same error pops up. I try to reinstall the driver and still to no avail. However, certain lower ports at the back do work, but they offer only USB 1.1. Does anyone have the same problem/fix? I appreciate any help you guys can offer.

Anybody? Please?

You don't put your system in standby mode do you?

[Diverge]

what operationg system are you using. XP w/ sp2? if so, what driver usb driver is currently installed?

 

here's a pic of mine system (XP w/SP2):

 

 

maybe try to connect your usb drive, then open device manager and see where it tries to enumorate (should be under 'enhanced'). try to uninstall the driver, and then reboot and see if it fixes itself. I'm not sure if this will work, but it's something to try.

 

it could just be an incompatability problem between the USB chip used onboard and your usb device. ex, my usb drive doesn't like to enumorate if connected into one of our usb hubs at work. But in your case it really seems like a driver issue, since it worked in the past.

I am running Windows XP Pro slipstreamed with SP2. I've never put my system in standby before either.

 

I'll try the fix with uninstalling the drivers in device manager. Unfortunately, my computer is currently at school (it was built for a Computer Tech class =]) so I can't try it out until tomorrow...sigh.

I've also had problems with my Expert's USB ports. Specifically the extra onboard plug-in ports.

 

I have a water cooled system and the pump has a USB plug that communicates with a software program made by Asetek to control fan speeds, pump speeds, temperature monitoring, etc.

 

Some times I will start the program and it initializes and comes back saying that the USB device cannot be found.

 

Restarting doesn't help either. A cold boot must be done (not that its a big deal) to make the USB device recognizable again... strange.

 

I have a flash drive and a USB mouse neither of which I've had ANY issues with at all which makes me point to the actual pump device that is having the issue and NOT the motherboard.

 

In other words, it could be a fault of the device not liking something in the BIOS or the board that just makes them work weird together.

I have the "Enhanced" USB driver. Uninstalling all the usb drivers didn't work. Everything reinstalled upon restart and nothing worked still. Sometimes the ports that do work with USB 1.1 dies too...and then comes back. When I tried to update the drivers on device manager it says it will connect to Windows Update but instead looks locally. Wierd. Is that supposed to happen?

 

I tried the drive in yet another computer and actually the same thing happened; the popup error says the device cannot be recognized. Perhaps it is a problem with the drive after all...I'll be able to bring the computer home tomorrow, (finally) so then I'll try out my printer and digicam and hope for the best.

 

Any more suggestions?

 

Thanks for all the help so far.

All with non working USB ports should go through all usb root hubs

in device manager and disable this :

 

 

After it's done recycle the PSU power (remove AC to kill standby voltage on motherboard)
