I changed the two function registrations to NULL, and got following message if plug in a USB mouse: hub 1-0:1.0: Cannot enable port 1. Maybe the USB cable is bad? hub 1-0:1.0: Cannot enable port 1. Maybe the USB cable is bad? hub 1-0:1.0: Cannot enable port 1. Maybe the USB cable is bad? hub 1-0:1.0: Cannot enable port 1. Maybe the USB cable is bad? hub 1-0:1.0: unable to enumerate USB device on port 1 And the host controller is dead (not responsive) after this. Thanks, Julie.
