And here is the basic problem. This issue is not an issue specific to
usbnet. It arises everywhere we have a specific and a general
driver. Hence it ought to be solved in generic way in usbcore.

Nor can we do this with a simple list of devices, as we cannot
assume that the more specific driver is compiled in all systems.
An unconditional quirk is acceptable _only_ if usbnet would
not work.

Please get in contact with the core USB developers. The problem
needs to be solved, but this is not a solution.

	Regards
		Oliver
