I’ve currently been messing around trying to make the Switch 2 Pro Controller work on Linux using the raw HID commands from this website, to potentially build into a driver as a bit of a project to get better at C. However, seemingly nothing I use can send any commands properly, or at least in a way that makes the controller work. I’ve tried both echo, sending bytes to the /dev/hidraw6 device (that device at least on my system, may vary on others), as well as hidapitester (a wrapper for hidapi). I know the device works, as a WebUSB tool that uses the same commands makes the controller work on this system. Is anyone more familiar with this, and can point me in the right direction? I’m on Fedora Linux 42 if that info helps.

It’s a channel for sim racing, but there are pretty knowledgeable people around that can get all sorts of obscure peripherals working on Linux.
