Hello Im new here. I have Win SE7EN Retail installed on my desktop PC and I am experiencing the same issue. In devmgr I have an Unknown Device. Device Type: Universal Serial Bus controllers. Device Status: Windows has stopped this device because it has reported problems. (Code 43).
I have two USB devices attached, a DELL mouse, and a Buffalo Ext. HDD. Both devices are working. I have tried to update drivers for the Unknown Device, Windows said it's updated. I tried to rollback the drivers, same thing. I tried to Unplug both USB devices and used my PS-2 mouse during t/s, same thing. I tried to uninstall the device while in devmgr and scanned for h/w changes. After a few seconds the Unknown Device would appear again.
Im a tech support rep for DELL I had resolved more than a dozen of the same issue before w/ customer's computers but I am out of ideas as to what is causing this error on my own Desktop PC.
Pls. help. thanks in advance.
