Comment (by waddlesplash):
I don't have any USB2 audio devices, no. At present, USB audio is rather
far down on my list, I'd be more than happy to fill you in on what I know
if you'd like to take a look at it (do find me on IRC.)
I don't know much about EHCI, so I can't help there, and I haven't tested
anything beyond USB audio with the experimental isochronous support in
XHCI. It is more than possible that some or more than just some of the USB
audio problems are because XHCI does not implement isochronous support
properly. I'm happy to help with the stack end of things, I just didn't go
further there because I didn't have anything (or anyone) to test with.
FreeBSD appears to have a "uaudio" driver which supports both 1.0 and 2.0
devices, you might take a look at that.
