Hi Li,

well, the drivers are exceptions from the generic handling, so creating an
exceptional rule (entry in hid_blacklist) for them is not that bad. OK,
it's not the nicest thing on earth probably, but serves the purpose in
current vendors-trying-to-break-hardware-in-the-most-original-way world
quite well.

This is going to cause some headache to out-of-tree drivers. Oh well, do
we care that much?

In your scenario you'll still need a way how to unbind the device from the
hid driver and bind it to the new specific device, won't you?. This could
be done by a separate userspace program, but well ... I think just
blacklisting the hardware is much cleaner, than needing to ship a separate
userspace program along with the driver.

Thanks,
