Ok - this is something to be compiled into the kernel - right?
Is it possible to add a quirk with usbconfig after the device is
already detected?
devd won't work since it won't say anything as config 0 won't
attach to any driver and ugen isn't listed there.
Also the devd data would be missing the bus number.
