Hi This is more of a general comment....
I'd try and steer away from USB audio... Reports in magazines like Sound on Sound and Audio Technology (an Australian publication) don't rate any USB audio devices highly .. due to the low bandwidth and shared nature of the USB protocol. i.e. the FOstex USB Midi/audio desk (sorry can't remember the model) can't handle full spec MIDI and all audio processes at one time... When using laptops it is highly recommended to use a firewire hard disk as your recording media as the latency of the hard drive on even the best laptops is unacceptable under any OS (especially when multitracking even just on output). >From reading the alsa-user-ML archives I have seen various reports. Basically ALSA has not written support for USB audio specifically as yet, however some people have had some luck in getting these devices to work. I would recommend posting a question to the alsa-user mailing list [EMAIL PROTECTED] (you need to be a member) to see how easily it has been done, and with which devices.. if this is your only option. My strongest reccomendation would be either to wait till there is a firewire audio device, with it's information released so that someone can write a driver specific to it. (i.e. not the MOTU or other devices currently out there). With any luck maybe the mLan spec will be available to open source developers at some stage.... and an mLan (firewire) device would be the strongest suggestion, especially with future studio expansion in mind.
