I tried to see what adb events my MicroSpeed Mac Mouse Deluxe was
sending to Mac, and as far as I can tell, it doesn't generate any
keyboard events... I think, from what I've read in _Guide to the
Macintosh Family Hardware_ 2nd Ed., it must be passing button values
by adb device register 1 or 2. Read from /dev/adb gives me register
0's value, but not 1 or 2. How do I read registers 1 and 2? The
current adb driver (i.e. mrg) simply calls ROM routines and Mac ROM
calls are all greek to me...
I appreciate any help
