I believe the firmware loader for using that device under Linux hasn't been released yet. I can see the point of moving the A/D converter outside the computer, but I don't think USB 1.1 has enough bandwidth for serious multitracking (eg four inputs/outputs or more). This doesn't matter with two in/two out cards like the Audiophile, but I think it becomes an issue with greater numbers of channels, where using the higher sample and bit rates with all channels at once could be a problem. USB 2.0 and Firewire should do the job, although I don't know of many of these devices with Linux support. Cheers! Daniel
