 Device reports 4 extra buttons (upper nibble of "Extended Capabilities
 0x40", and yes the debugging printf is misnamed), but the driver only
 knows how to handle two extra buttons: see "New up/down button" case
 that only checks the least significant bit in psc->packet[] bytes 4
 and 5.
 
 New touchpads encode up to 8 extra buttons in low order nibbles of
 those bytes.  Driver should remember the number of extra buttons
 reported by the device to know how many low order bits of
 psc->packet[] bytes 4 and 5 to look at.
