at least I have a cheap Terratec Aureon USB which can deal with 

OTOTH, when calculating the USB bandwidth vs. the needed data amount at 
5.1, an USB 1.1 bus is almost completely busy with audio.

There's USB 2, but the audio standard has not been expanded for USB 2 
and that's why there are only a few USB 2 audio devices, and those you 
get speak a proprietary protocol :( .

Best regards
