USB hub broken between 2.4.10-pre6 and 2.4.10-pre12

USB hub broken between 2.4.10-pre6 and 2.4.10-pre12

[lkml]

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):

It looks like your hub is working, for a while, then it starts having
problems.
Is this hub powered from the USB bus, or from an external power supply?
Does your devices still work properly plugged into the computer
directly?
