A USB HID report ID must be represented using a single byte ranging
between 1-255 where 0 is reserved. The pseudo report ID
UHIDEV_CLAIM_MULTIPLE_REPORTID is currently colliding with the valid
report ID 255. Therefore crank it which gets rid of the collision and
increase the related fields in order to cope with larger integers.
Thanks to Damien Couderc <openbsd at petrocore dot eu> for reporting and
testing.
