I'm having a nasty time trying to nail down what's going wrong. It seems that for kernels 2.6.17 and earlier, MIDI works fine through this interface. After that, it doesn't. Most bizarrely the Dynebolic distro, which is designed specifically for music, doesn't work with this interface. This leads me to believe that something changed with 2.6.18 that the MOTU Fastlane didn't like, but doesn't bother other USB MIDI interfaces. Here are some notes from my bugtracking: Doesn't Work: =============== Dynebolic (kernel 2.6.18, ALSA 1.0.12rc1) Ubuntu 7.04 (feisty faun) kernel 2.6.20-16 Fedora 7 (kernel 2.6.21) Works: ====== Gentoo 2006.1 i686 Live CD (kernel 2.6.17) If the interface is attached at bootup, one gets "cannot determine device number: Inappropriate ioctl for device". After unplugging, then replugging a couple times, midi works ok.
