2.6.12-rc5/2.6.12-rc5-git8 USB problems

[Sid Boyce]

Everything works OK on 2.6.12-rc4. The joysticks are seen by lsusb and 
the joystick test programs, but the controls do nothing in 2.6.12-rc5 
and 2.6.12-rc5-git8.

The consensus from Dmitry and Vojtech is that this could be either USB or
an input layer problem, but nothing changed in [UO]HCI or HID between the
two mentioned versions.

So this is more likely a recent regression in the USB code.  Could someone
please grab it while it's fresh?
