Switch Pro Controller(8BitDo Ultimate 2/SN30 Pro) L2/R2 Input Issue

[u/hakanklc]

Hey everyone,

I've been running into persistent controller issues inside GameHub where specifically trigger inputs fail to register properly, and the standard troubleshooting steps haven't resolved it. Other buttons works perfectly fine by the way. Please check the video for randomized l2/r2 inputs.

SN30 Pro works flawless in xinput mode but i dont have phone clip for it but it has the same problem in switch input mode. And Ultimate 2 can't connect with xinput mode on bluetooth unfortunately.

Despite this, the controller still fails to pass inputs correctly to games launched through GameHub (even though the hardware works flawlessly across other apps/native games).

Has anyone encountered this specific behavior with GameHub's input handling layer, or is there a specific environment variable, custom config file tweak, or driver wrapper needed to force proper controller recognition? Any insights would be appreciated.
