USB problem... "Unknown Device"?

[NewMan]

OK dig this...

Relatively new system, been running fine. Used many USB flash drives -
no problem.

All of a sudden USB drives when plugged in generate an "Unknown
Device" message?

These USB drives work just fin in other machines, and there is nothing
wrong with them.

As a result of the error, the drives *do not* appear in the logical
disk manager.

Also, I have an APC UPS that is connected via USB, and the machine
cannot talk to it now either!

Yet, the USB mouse and keyboard are OK.

I'm stumped. I did some Googling, and have come up dry.

Any ideas would be appreciated.

Many issues with USB's as of late. Generally after ipod use.
