USB hub broken between 2.4.10-pre6 and 2.4.10-pre12

After upgrading from 2.4.10-pre6 and -pre12, my USB hub stopped working.
This happens with both of the UHCI drivers.  If there's anything I can do
to help (narrow it down to a specific release?) let me know...

Here are the USB-related kernel messages (the interesting stuff is, of
course, at the bottom):
