the most salient thiing you could do is find the date of the problem by checking
out sys/dev/usb on dec 9 and seeing if that fixes it (you said dec 9 was ok)
and if so, gradually moving it forward using a binary search and narrowing in on
the commit that broke it.
Is it an ohci or uhci (or ehci) usb inerface?
