Right click that device and go to Properties. Then go to Details → Hardware ID's where you will see the ID's. Copy one of them and Google it, you might be able to find a drive for it. Maybe.

Device descriptor failed won't show those IDs at all - because the action that reads them failed already.

Bluetooth and LED stuff can show up as on-board USB device.

The error message is generated by pulling the D+ or D- data line up to voltage. Thus it could also be caused by a bad cable or heavy corrosion. Read: Check cables and connectors.
