USB device not recognized.

USB Audio Device Properties
Device status:
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
It's a USB microphone, and it was fine until the Pro|Type Keyboard Driver update. Device Manager shows Device Descriptor Request Failed. i've tried rebooting and a few different ports. Sometimes it works for a moment then disappears. i'd like to understand what this error actually means and where to start troubleshooting. The device itself seems fine, it works on another computer without any trouble. i'd rather not buy a new one if this is smth on teh PC side.
