As it happens, I was playing with the ADB manager recently.  :-)

The trackball emulates 2 devices:  an Apple mouse (device type 1,
original address 3), and an Apple Extended keyboard (device type 2,
original address 2, remapped to 0xF on my system because of the real
keyboard).  The keyboard device is there for the extra button on the
trackball which emulate keypresses.  You can program which keystroke it
sends with a 'listen 1'.

If you want me to find out how it responds to specific ADB commands,
let me know.
