Hi,
Alan Stern has written a change to the generic autosuspend mechanism that
allows timeout based suspension. As he suggested I've tested it by using
it for suspension of HID devices. It took some small changes to Alan's code
to introduce a bit more flexibility. It's tested with mice but needs review.
To allow testing I am posting the full amalgated patch against 2.6.20.
I'll also put apart the patches.

Hi,
you need this additional patch to fix an oops with driverless devices.
Regards
Oliver
