2.6.29.4: /proc/bus/usb is empty

[Chris Frey]

Hi,

I recently upgraded from 2.6.28.9 to 2.6.29.4, and oddly /proc/bus/usb
is now empty.

The devices show up nicely under /dev/bus/usb, but I hadn't noticed
anything indicating that this would be moved.

/proc in general appears to be well populated.

What could cause this?  I can post configs and config diffs if needed,
just let me know.

Thanks,
- Chris
