Re: [RFC PATCH] HID: support the NACON / BigBen PS4 / PC Compact controller

Hi Giuseppe,

Thanks for your work so far. My first thought was 'yikes what an ugly
device'. I'm not really sure what the best way of handling it is.

First is the device a HID device? It would normally be picked up by
hid-generic. You can try dumping the HID descriptors.

It is a bit ugly if the device has to spawn multiple drivers. My
initial gut feeling would have been to complete the support within the
xpad driver. My understanding of our licensed controllers is that the
HID protocol they use is different from the DS4 protocol, so it is
really like handling an entire new device needing its own HID report
parsing. So, no matter what each driver would have needed some changes
to deal with the device properly and it is probably smallest in xpad.
You mention access flipping and then the touchpad.

Thanks,
Roderick
