Just replied to the other email, but this one is a nak until we have the
Documentation/input/event-codes.txt patch with it explaining how this code
should be used, what these codes represent, what the interaction is with
other codes (e.g. can a device send wheel and hires wheel at the same time?)
etc. There are a lot of questions left to be answered.

Cheers,
