USB Flash Drive Not Recognized

Hey all,

I recently bought a 512 MB PNY Flash Drive (USB 2.0), brought it home,
and it worked great for about a week. Then all of sudden yesterday, it
refused to be recognized. I run Windows XP home, so it SHOULD have the
driver for the device. Here's what happens:

I plug it in, and it says "Found new device." Then it says "There was
an error installing the device. You should re-plug the device or
replace the device." Ha, false on count 2. The device is still good
because it is recognized on other computers. I tried uninstalling the
driver, but then as soon as I plug the drive back in it just repeats
itself.

So I checked in Device Manager. It's listed as "Unknown Device" under
the USB category, but there is no exclamation point to it. I click on
it, and it says there's no driver for it!

And yet Windows HAS the driver...hm...

Any help is appreciated, thank you!

Yeah, removed the "Unknown Device" driver in Device Manager (which is
what it installed for it). Then when I re-inserted the drive, it just
re-installs the "Unknown Device" driver =\

What about the USB controller--do you see nothing connected to it in DevMgr
(while the flash is plugged in)? I've seen the controller reinstall when I
inadvertently deleted it, and after a reboot it found the flash drive when I
plugged it in. Of course I have to have about the flakiest XP system
around, so this may be no guide.
 
How do I look at that, the USB controller? How does it change whe
there's something plugged in?

Here's the strange thing. I'll do a System Restore, and then all of
sudden the USB drive works fine. Then about 3-5 days later it STOP
recognizing again, and gives me that error again.

What all does System Restore do/change? And what might keep comin
BACK onto my system that's knocking the USB out of commission?
Thanks!
 
What I meant was to look in DevMgr--If the thumb drive is plugged in, you
will see it there, depended from the USB controller. As far as the System
Restore, what you'd be doing there is using a version of your registry that
is older than the one you're currently using. Sounds like you have
something on your computer that's doing this.

I have a similar problem.

I expected to see the USB flash drive appear in Windows Explorer listed
under My Compuer alongside A:\ C:\ and D:\ etc etc.

I decided to do a search for a file that I knew was on the flash drive, and
it was found. The flash drive was assigned the E:\ drive and was located in
Control Panel, Portable Media Devices. So I can expand the drive in Windows
Explorer and use the files as normal. The only issue remaining is that every
time I insert the Flash Drive, Windows tries tries to instal drivers... I
then need to cancel this. I still do not need to do this on my other PCs
with the same Flash Drive.

Also under Portable Media Devices is Nero Fast CD Burning Add In. I
wondered if this could be causing a conflict of some sort. It is supposed to
be used with Windows Media Player 9 although I have WMP 10 installed. Do not
know how the add-in got in there.

Does your device appear in the same place on your PC??

Click to expand...
 
i also had the problem. This worked for me. I set the usb flash drive
as B:\ using right click on my computer, click manage, click disk
Management,right click usb flash drive(probably E:\), click change
drive letters and paths, click add and change to drive B:\. then ok
everything out. Reboot. I also uninstalled nero but do not know
if it had anything to do with the problem.
 
Found a solution that worked for me.

It would appear that, when new hardware is identified, Windows XP Home does
not automatically look in the c:\windows\inf folder for the driver. When I
told the wizard to look in that folder, the drivers were loaded with no
problems and everything is fine again.

What has caused this, I do not know...but all seems ok now.
