I also saw the problem with 2.6.36-rc3. My problem is with
usb_find_interface(&hiddev_driver) not finding anything and
9c9e54a8df0be48aa359744f412377cc55c3b7d2 did not change this line.

In its current state I don't understand how hiddev_open() can possibly
work. I see people reporting suspend issues and stack traces in dmesg
but nobody reporting the driver being non-functioning, which is what
I'm doing here.

Thanks.
