The spec states that the HID devices should allow
the host to query the HID descriptor at any time.

Some devices require the HID descriptor to be set
on resume, or they will fail.

Instead of having a growing list of blacklisted devices
make the call part of the general resume process
so we can remove this list.

Jiri, please hold with this patch, Canonical might have found a better

Thanks for the heads up.

In case that's the case, please also send a reference to the subsititute 
patch submission into this thread, so that archives to pick it up :)

Thanks,
