As M-Audio generously denied providing you with one (haaaa, these big corporations), I'm ok getting a brand new one sent to you. That would be part of my donation to the open-source community!
Wow, that's quite an offer, I'm impressed. However, I would really only need a device during development to hook it up to an USB analyzer and have a look at the dumps. And having access to one would definitely speed up development. Once the issues are fixed, though, I can give it back to you or to someone else who actually uses the device afterwards - I've got enough sound interfaces around here :)
As bad as it sounds, I can hardle spend a day without playing music, and my soundcard is the central piece of my setup :)
But feel free to sale the device back when you don't need it to get yourself another device that needs debugging! Or you can always make a donation to Ardour or Hydrogen, God knows they need it!
