USB host mode #11

Closed pipcet closed 3 years ago

It appears USB host mode is totally broken right now. I don't use it regularly so I hadn't been aware of it (USB gadget mode works as it always used to).

The question is whether to bisect this, or switch to the Asahi-based branch I've been working on anyway, where it works. The problem with the second option is that the Asahi people chose to move initialization that I feel really belongs in the Linux driver to m1n1, and I might have to move it back.

The current state is that with some driver hacks, USB host mode, USB gadget mode, and USB power delivery all work; there's still software intervention required to successfully disconnect devices and prepare for connecting the next device, but no reboots are required at this point.

Okay, I'm closing this issue as things appear to work now. USB ports on the MacBooks should work for PD, host, and gadget mode; USB ports on the Mini are all in host mode. (This can be changed, but autodetection doesn't currently work).
