Hey everyone,
This is my first USB project and I'm not quite sure where to go at this
point. I've already asked around the libusb forum for help to get started
with various information, docs , etc... I've now successfully analyzed my
snoopyPro logs. I also have charted out and verified (with the docs ...
not programming) the HID Usage Pages printed out to me with the lsusb -vvv
and the libhid libraries installed.
(see attached)
Now the question is how I take this information and write it into code.
I'm using the Python Bindings.
Any help would be appreciated.
Thanks
Christopher
