Hey everyone, I recently created this website: http://www.linuxstudiopro.com which contains a list of all the linux compatible pro-audio hardware I could find. It's mostly interfaces with a few MIDI controllers. I think that everyone here could benefit from using this list, since so many of you are posting questions about what device will work with your system. If any of you have additional hardware that you use please let me know. Also, if you are familiar with a product on the site, please leave a comment and rate its compatibility and performance in Linux.
