I'm using virtualhere through the original steam link hardware. I bought an old skool gamecube to USB adapter. I updated the firmware using zadig (link below). When I plug the adapter directly into my PC, dolphin emulator sees the gamecube controller like normal. When I plug it into my steam link and pass the adapter, dolphin doesn't detect the adapter. Steam sees a Betop BFM Gamepad in addition to the dualsense I have attached too. I tried disabling steam input, but that still doesn't resolve the issue.
Has anyone ever gotten a gamecube to USB adapter working through Steam Link hardware? I don't mind buying the official adapter or a different 3rd party brand if it means it'll work.

I dont know sorry. You will probably just need to ask on the steam forums.
