Hi Dmitry-

Thanks again for your review.  The forthcoming PATCH v6 addresses all of
your requests, except for:

This device (my particular Cypress Trackpad unit anyway) does not have
physical buttons.  The pad is clickable; I think it is a standard
"buttonpad" device.



And just FYI, this issue has been addressed but to answer your question:

It can: in the case when the mode hasn't been set at all yet (during
detect and reconnect).  I cleaned up the logic of this routine
(cypress_validate_byte) and added explanatory comments.
