Hi,

I'm working on this issue. I have a machine with SSH which has the exact same 
problem. It seems like it is UHCI related! I have a patch you can try:

Edit "..../usb2/controller/uhci2.c"

And change:

UHCI_TD_SET_ERRCNT(3)

Into:

UHCI_TD_SET_ERRCNT(0)

Recompile and re-load "usb2_controller_uhci".

--HPS
