Given below is the debug o/p from usb-uhci,strangely it seems to
skip the frames after 118 it jumps to 145  .. similar is the
case with frame 0 , it doesn't load frame 0 rather jumps to
frame 1.The guest is minix 3.1.5 and the o/p was generated
from the driver under development,i have notice the same
behavior with NetBSD
