USB gadget #27

Open dogtopus opened 2 years ago

dogtopus commented 2 years ago

With libraries like python-functionfs it should be possible to reuse some existing HID code in nxbt and make a USB gadget on Linux that emulates the Pro Controller. (For example my PS4 controller emulator/protocol testing ground uses it)

(One thing worth noting though is that python-functionfs in particular starts up as root and forks as a process under normal user for security reasons and needs to be take into account when cross platform is a goal)

This is an interesting idea. What you're suggesting, if I'm understanding correctly, could be a Raspberry Pi Zero W emulating a Pro Controller but plugged into another computer. The host computer (that the Pi is plugged into) could send commands to the Pi?

I would definitely be willing to investigate this more when I have bandwidth for new features. I'll add an enhancement tag for now, though. If anyone else wants to investigate this or provide extra details/wishes, feel free to comment.

Pretty much except that the computer can also be a Switch (i.e. you plug the Zero W in, it gets picked up as a wired pro controller and it starts there).
