Invisible Flash Drive (long)

Guest

Please read the whole thing. Sorry for the length. Thanks.

Problem:
PC won't assign drive letter to flash drive (USB mass storage device)

Equipment:
Windows XP Home
EnPower Nitro 4 with AMD Athlon 64 3200+
Lots of RAM, lots of hard drive space.


History:
Trying to update my video drivers and being unsuccessful, I did something
that sent my PC into a coma. Computer shop resurrected it without loss of
anything. Even the desktop, the way I had arranged icons, was exactly the
same. The shop upgraded my video drivers for me. All appeared to be back to
normal.

I plugged a flash drive (USB mass storage device) into a USB port. The PC
made the happy "dong-ding" sound. Little yellow boxes popped-up in the
bottom right corner of the screen saying things like "New hardware found,"
"Installing hardware or drivers," and "Your new hardware is ready to use."

However, when I look at Windows Explorer, I can not find the drive. In
Device Manager, I can see the USB flash drive listed. Clicking on it, the PC
indicates that it is working fine. When I click on the green arrow in my
icon tray to disconnect, it is listed as flash drive "USB mass storage
device" but has no drive letter listed with it. When I click to disconnect,
then remove the flash drive, the PC makes the happy "ding-dong" sound.

I asked the computer repair shop techs, but they had no idea. All three of
my flash drives work on other Windows XP computers, but not mine. My Palm
PDA is connected to my PC using another USB port and has continued to
communicate well with the PC no matter what changes I make.


What I have tried:
I have tried leaving the flash drive in while I log off and log on.
I have tried leaving the flash drive in while I power down and power back up.
I have turn the PC off and unplugged it for 30 minutes.
I completed every available update from Microsoft update.
I learned that the "Hide and disable all items on the desktop" system policy
may be an issue. I don't know what this is, but everything on my desktop is
active and happy.
I downloaded and installed a zip file ("USBDLM") from the internet
(http://www.uwe-sieber.de/usbdlm_e.html) that is supposed to re-letter the
USB drive.
I have assigned a variety of drive letters to the flash drive using
Run/diskmgmt.msc (it has no letter initially), but the lettering didn't take
effect.

I'm looking for clues, thanks for reading all of this.

Just a thought to try (and there is probably a more technical way of doing
this) download TweakUi from windows powertoys, and check in the "My
Computer/Drives" section, and see if any drives are flagged as being hidden?

Also have you tried the USB on another machine?

Regards
