For a few sweet days, I was running a Presonus Audiobox 1818vsl on linux. Now for the last couple of days, I am not. I still don't know why, but one of the things that has changed is the firmware upgrade to 1.19, which I did from my OS X box while trying to figure out what has gone so horribly wrong. (I've been unable to work for two days, yay.)
I don't know what version of firmware was originally on the 1818vsl, but when things were working, it was not this version and I'd like to try going back. Help?
