Commit 93c8bf45e0 modified the USB device
matching behaviour to ignore interface class matches if the device class
is vendor-specific.
This patch adds explicit ID matches for Logitech QuickCam devices, which
have a vendor specific device class (but standards-compliant audio
interfaces).
This fixes a 2.6.20 regression where the audio component of these
devices was no longer usable.
