I think both: 1. adjust the HID descriptor into something that can be more easily remapped; 2. remap the keycodes in hid-sony to those of the gamepad API, because AFAICT that can't be achieved by solely deciding HID usage codes in the descriptor. > Do you have example of another driver to copy? I am doing some work already in this direction, on the lines of what we did for the ps3remote in hid-sony, but it needs some input bits not merged yet, I'll send an RFC as soon as this becomes more easily testable.
