Yes, hid provides very comprehensive documentation and debugging tools that you can use for this.
Open the hid help patch (you can find this easily by creating an [hid] object in a blank canvas and then right clicking (ctrl+click on mac) and selecting help. This patch will be very useful to probe the data sent from various devices.
Next, click on the message box labeled [print( and look at the output in the Pd console. You will see a device list that numbers each device starting at 0 and also gives a brief description of the device.
After you find your device of choice, click on the radio button corresponding to it's number, or if you prefer send a message [open n( where n is the device number that was printed in the console.
Now that your device is loaded by hid, try giving it some input and observing the various number boxes and toggles to get a feel for the range and style of output that your device offers.
I hope this helps! Happy hacking.

Hey there. Not sure where or who to direct this to, but I recently watched a video tutorial on youtube on how to modify your laptop's trackpad into a MIDI-control device much like a Korg Kaossilator:
http://www.youtube.com/watch?v=uWE2ptQtYk0. Apparently the creator of this video created a patch to create this device, but the according to him it only works with Synaptics track pads. I'm running a newer aluminum macbook with a MultiTouch track pad, and was wondering if anyone has figured out a way to get absolute positioning information, and possibly multi-touch info as well, into Pd to Midi notes in appropriate scales. Any kind of help would be appreciated, as I'm trying to get my music rig set up to be super-fly.
