Hmm, a long time ago - this was on Windows XP - I remember using a
http://www.esi-audio.com/products/gigaportag/ and I don't think we
installed any special USB drivers for that.
8 channels * 48000 Hz * 16 bit ~ 6 MBit/s, and we're talking about the
12 MBit/s version here, so I guess it should be enough even with some
packet overhead, but maybe some of the more broken USB host chips have
some problems with it?
