Message-ID: <Pine.GSO.4.55.0708100242000.25856@helios.cs.csubak.edu> Date: Fri, 10 Aug 2007 02:42:34 -0700 (PDT) From: David Griffith <dgriffi@...csubak.edu> To: linux-kernel@...r.kernel.org Subject: MOTU Fastlane USB MIDI interface Does anyone here have or can borrow a MOTU Fastlane USB MIDI interface? 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. Ubuntu 6.10 (edgy eft) (kernel 2.6.17, ALSA 10.12rc1) Knoppix 4.0 -- David Griffith dgriffi@...csubak.edu - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
