Comment (by danboid):

The main and only real OS/driver level issue that prevents me switching to
Haiku from Linux is that I cannot use my USB audio devices (such as the
Focusrire Scarlett 18i20 and 2i4) via EHCI.

I have a few questions for siarzhuk I hope he's kind enough to answer:

* Will the Haiku USB audio driver get enabled when we have isochronous
streams working under EHCI or will we have to wait for XHCI to work too
before that happens? The latter would seem silly to me. Is there even such
a thing as a USB 3 only audio device?

* Does the Haiku USB audio driver support audio input, unlike OSS? Should
it be able to recognise and use all 8 XLR inputs on my 18i20? Both my
Focurite devices are USB class compliant and work great under ALSA/Linux.

* Is there any support for S/PDIF in the USB audio driver yet?
