USB Device Not Recognized - is there a basic reset?

[Steve]

My computer almost always fails to recognize USB devices when they are
plugged in to any of the USB ports. I get the "USB Device Not
Recognized" message. Some, I can get to work if I power down, plug in
the device, and reboot. Others, like a thumb drive that works fine on
several other computers, I can never get it to recognize. They alsways
show us as UNKNOWN DEVICE in the Device manager and no amount of
troubleshooting or web searching has helped. Device manager shows 5
root hubs, and 5 host controllers - but I can't tell what is what.

The USB wireless mouse/keyboard and printer work fine but no other
devices ever have worked without a hassle.

I've had these problems with 2 external drives, two different digital
cameras (Canon's help couldn't figure it out either), and flash drives
that work fine on similar computers.

Suggestions for a fix?

My Dell computer is 3GHz Pentium4, 2G RAM, Windows XP PRO, SP2.

TIA

Steve

Question: Is this true for all USB peripherals, or does it work for USB1
peripherals and not for USB2 or vice versa? Can you give me full details of
something that works and something that doesn't. From you description, I
figure that your PC has 8 USB ports and should work with USB2 periperals
(Please confirm).

A "me too" reply is unnecessary, especially for a 14-MONTH OLD thread. No
one is monitoring that thread that previously participated in it.
