USB Camera and Scanner Show Problems in Device Manager

Guest

I have a USB camera that used to connect fine on my USB port and just bought
a scanner that refuses to connect. Both show icons with yellow "!" marks and
device status messages of "Windows cannot load the device driver for this
hardware. The driver may be corrupted or missing. (Code 39)" in Device
Manager. I have uninstalled/reinstalled both (using both Device Manager and
Add/Remove Programs) but the same problem occurs. Tha camera give 3 short
low-low-low beeps when connected (as opposed to the 2 low-hi beeps when it
used to conect successfully) Any suggestions? I have an Intel Dual Core
[email protected], 2GB RAM, XP Media Center 2002 SP 2 (fully patched), 157GB disk.

Go to Start/Run, and type DEVMGMT.MSC , highlight the USB Hub device(s),
Action menu, "Uninstall", then restart Windows, to find the device drivers
again automatically.

Mark, thanks for the response. However, that didn't solve it. After playing
around a couple of hours, here is what I notice. All other types of USB
besides imaging work (iPod, printer, pocket pc, disks). Only the imaging USB
devices won't. What's really frustrating is that the multi-function
printer/scanner will let the printer work, but not the scanner. I verified
the scanner does work with another PC (work laptop). When I went into Safe
Mode, it appeared that the scanner was ok (no yellow !) but the printer
wasn't (it had a yellow !; said RPC service needed to be running and it can't
in Safe Mode), but the scanning/imaging software still did not recognize the
scanner or camera. Is there a service or other setting that needs to be there
for imaging USB devices that is different than for printer/iPod/disks?

OK. Figured it out. Using Regedit, I went to
HKEY_Local_Machine\System\CurrentControlSet\Enum\USB and looked at the
sub-items that had a Class of Image. I noticed they all had the same Driver
key. Searched for that key value and noticed it had 4 items under it. One of
which was a Logitech webcam that I had uninstalled. I reinstalled the
Logitech drivers and setup the webcam and all the other image devices started
working. Go figure. Gruelling but worth it.
