Description Anthony Pesch 2019-10-08 00:22:02 UTC 
Hey Sam,

I saw you committed the original Switch controller support and wanted to ask if you had any idea why the wired variants of the Switch controller fail around:

https://hg.libsdl.org/SDL/file/db9d0d0b7ebc/src/joystick/hidapi/SDL_hidapi_switch.c#l596

I've had users with:
https://www.amazon.com/Nintendo-Switch-HORIPAD-Controller-Officially-Licensed/dp/B01NAUATSM/ref=sr_1_3?crid=19VSH28WFGAHE&keywords=wired+switch+controller&qid=1570493099&sprefix=wired+switch+%2Caps%2C175&sr=8-3

as well as I believe:
https://www.amazon.com/PowerA-Wired-Controller-Nintendo-Switch-Black/dp/B07PDJ45BT/ref=sr_1_6?keywords=power+switch+controller&qid=1570493866&sr=8-6.

report their controllers not working due to the above error. I was trying to avoid buying a controller I didn't really need to come up with a patch, so I wanted to ask here first if you a.) happened to have one to test with or b.) had an inkling as to why that was failing.

Hey Sam,

Just got hit with this again tonight.

If you have any input I'd appreciate it.

Have you tested it with the latest SDL source code? These two changes went in recently which seem like they might fix your issue:

Fantastic, I'll give those changes a shot tonight.

I think this was fixed, thanks!
Comment 5 Anthony Pesch 2020-01-08 02:03:37 UTC 
While this is already marked as fixed I wanted to confirm it from my end, thanks for the patch Sam.
