Hardware Identification

Hi everyone:

I have a problem trying to ID a piece of hardware in my system. I am running XP in a P$ machine, and when I boot up, I get the p & P message that a certain piece of hardware does not have drivers installed. In Device Manager, this hardware has the big yellow ?, but I have no clue what this hardware is.

The only thing I get is what appears to be some sort of ID number:

VID_04E6 PID_80000040

Can anyone assist me in learing what this is and direct me to a utility that scans MB to ID installed hardware? Thanks in advance. All help is much appreciated.

John
