[LAU] USB Mixers

I'm looking for a new mixer and wondering if I should bother with one of the USB units. From what I read they will send a signal back to the computer for recording. Cool. Not something I'd use everyday, but might be handy when I think I'm doing something good enough to record/share :) Now, I also see that they seem to use USB 2. Is that a linux problem? Would a moderately new desktop keep up to a multitrack usb stream? I'm assuming that these units send multi tracks to the computer unmixed? Or is it just a copy of the 2 channel out? Here's one example: http://www.music123.com/Pro-Audio/Mixers/Unpowered-Mixers/XENYX-X1622USB-US… Not sold on Behringer or this model, just looking around today.
