Hey David D., I was able to improve the situation with the patch below,
basically that's what I am doing:
- In the descriptor have two collections, one for "joypad buttons"
which allow multiple keypresses, and one for the remote buttons
which do not allow multiple keypresses.
- Have two key maps, one for each collection.
In order to make this work I have to put joypad buttons only in one of
the key maps, I don't know if that is compatible with the Harmony
adapter.
BTW to deal with HID descriptors I am using this gHID tool which
provides a "smart language" that ease things a little bit:
http://code.google.com/p/ghid/
The code spacing and naming of variables can be improved in the patch
below but I wanted to get it out ASAP to avoid duplicate work.
Regards,
Antonio
