The gc-linux project had such a bus driver, and I think also an USB Gecko driver, but from what I remember they got rejected in the kernel. I’d have to do some archeology to figure out why though. Still, maybe it would be sensible to port their 2.6.32-era driver? I have one such USB Gecko btw, so I should be able to test against it. > > (But I realize it might be significantly more work.
