I'll dig into this more when I get home and have the proper tools at hand. I think it's unlikely that apcupsd has gone wild because we don't see a barrage of control messages passing thru the HID layer. > > Unfortunately, current usbmon cannot tell if usbfs tried to unlink > > the stuck control.

Does usbfs get involved with transfers originating from the HID layer? --Adam ------------------------------------------------------- This SF.Net email is sponsored by: NEC IT Guy Games.
