Not that I can currently distribute.
Converting to html, trimming out hardware detail, and feeding it through
channels for ALPS to say that they are comfortable with the amount of
data being released is on my todo list, but behind a few other things.
I see. Well, if you have a decent contacts in ALPS could you ask them
if they could release any information on their other hardware?

Hardware is wired with one device, which is quite wide. The entire
width can be accessed via the PT sensor, and the middle 1/3rd with the
GS sensor.
I believe that the buttons will be one on each side, though I'm not
positive, and the PT data, the GS data, and the button data all arrive
in the same packet.
So really there is no 'right' way from the kernel driver's point of
view, the buttons belong equally to both.
The kernel driver that this will be matched with will probably leave it
as a user configuration setting as to which one it will throw button
presses away for.
OK.

To match the first one, with a protocol name of OLPC and a vendor of
OLPC we end up with 'OLPC OLPC' for the first one, this is, IMHO, rather
suboptimal, but I'm not sure what else to do here.
Should not vendor be still ALPS?
