computer not recognizing USB devices

May 20, 2009 at 19:44:18
Specs: Windows Vista

My computer recently stopped recognizing when I plug in certain USB devices, such as my iPod, or a memory card adapter. When they are plugged into the USB port, the computer says that it is an Unknown Device, and I can't find a way to fix it. I tryed looking in the Device Mananger, and everything seems to be working properly. The USB ports won't recognize several iPod connectors and the memory car adapter, but it will recognize the plug-in to the printer. I'm at a loss, so if you could please give me any advice I would appreciate it so much.

Try checking in the BIOS that USB is enabled

I have the exact same problem -

Vista 64bit pre-installed on an HP Pavillion PC, Model a6750Y

When I insert a mass storage device (USB Hard Disk, USB Thumb Drive, CompactFlash or SD Card), I hear the "beep-beep tone that a new device has been found, but it never shows up in MyComputer. I can only open it by going to Computer Managment/Disk Managment and opening the drive in explore from there.

Has anyone else seen this or have any tips for me to loook at?

(HP support was no help, but they did send 20-minutes online with me).

Thanks,
Steve Mann
