[hid] is for USB devices so no.

http://www.gigamegablog.com/2012/11/04/beaglebone-coding-101-i2c/ talks 
about using i2c and python with the beaglebone which is a similar 
machine. It even uses code written for the Pi 
(https://github.com/adafruit/Adafruit-Raspberry-Pi-Python-Code). Using 
python ans OSC seems to be the easiest way to get started.

I just got one of these and I'm going to try it with an arduino since 
the i2c there is easier to use. The arduino can talk to Pd using [comport].
