Post it along with the usbmon log, and I'll try to figure out what happened.
Here it comes:

Corresponds to numlock; 7; numlock; 7.

Alan, sorry for the previous bad post, I mismatched 2 files. This is hopefully correct.

thanks. Could you also please redo the test with the offending uhci patch reverted and send the output of a working situation?
