[RFC/HELP] add support for POWER-A/THQ BDA NSW Nintendo Controller

[Ethan Carter Edwards]

Hello all,

I have an unofficial USB Nintendo Switch Pro controller that I have had
for a few years and want to try to use on Linux. For reference, the
vendor id and device ids are as follows:

Vendor: 20d6
Device: 0002

I tried adding the device to the hid-nintendo module to add support but
that did not work (see below for code). I recieved a few errors from dmesg

nintendo 0003:20D6:0002.0011: Failed to get joycon info; ret=-110
nintendo 0003:20D6:0002.0011: Failed to retrieve controller info; ret=-110
nintendo 0003:20D6:0002.0011: Failed to initialize controller; ret=-110
nintendo 0003:20D6:0002.0011: probe - fail = -110
nintendo 0003:20D6:0002.0011: probe with driver nintendo failed with error -110

I understand that -110 is a timeout. But I don't understand much else.

And I am not sure where to go from here. Any suggestions?

Thanks,
Ethan
