I'd appreciate if you'd implement this generically.

I.e., use the driver_info field of struct usb_device for an appropriate
blacklist flag. (It's not going to be the only one.)

Sure. I'll have a look into that ASAP.

Could you do me a favor and apply the first two hunks (i.e. add the vendor/device id) in the meantime?

This makes the driver functional in general. And - ehrm, would save me some time, because these hunks have to be rebased frequently. ;-)

The 3rd hunk (we're talking about) is just an "optimization" to make impatient userspace applications happy...
