It seems to be acting like Uthe USB controller isn't getting interrupts.
Does the problem recur on the installed system?  If it does, can you build
a kernel with USB_DEBUG, bump up the hw.usb.debug sysctl to like 5 (I
think thats what its called) then plug it in and see what you get?  You
should get a huge amount of spew if its working normally, or it'll slowly
trickle out sets of messages if its having problems getting the controller
to behave.
