Hi Marcel,

the specialized driver could hook on all reports of the device (as
discussed a few mails ago in this thread) and have the possibility to do
three different things with the obtained report:

- pass it back to generic hid driver for "standard" processing
- process the report, and issue input_event() itself
- pass it to hidraw and let userspace to consume it

This is going to work for the scenario you have described, right?

Thanks,
