I also have usbcore loaded (using snd-usb-audio), not sure if that is relevant. Maybe try loading usbcore before you plug in the midisport? > and the log reports the same when plugging in the 2x2: > > Mar 22 19:14:08 umatic1 hub.c: new USB device 00:1d.0-1, assigned address 36 > Mar 22 19:14:08 umatic1 usb.c: USB device 36 (vend/prod 0x763/0x1001) is > not claimed by any active driver. > Mar 22 19:14:11 umatic1 /etc/hotplug/usb/ezusbmidi: load > /usr/share/usb/ezusbmidi/ezusbmidi2x2.ihx for 763/1001/1 to OK, nearly there! I think your midisport 2x2 is missing from modules.usbmap. Go to /lib/modules/`uname -r`/ and grep 763 modules.usbmap. You'll probably won't have a line for 0x1001 (in the 4th column). You can add it here. Best copy one of the other lines, like snd-usb-audio 0x0083 0x0763 0x1002 0x0000 0x0000 0x00 0x00 0x00 0xff 0x00 0x00 0x0 Take care with the tabs! (I moused this one in). I'm on a 2.6 kernel here, but I don't think this was different in 2.4. FYI, myself I use some slightly different tools from http://usb-midi-fw.sf.net. Look like you can also create /etc/hotplug/usb/midisport_fw.usermap with: midisport_fw 0x0003 0x0763 0x1001 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 in it (no tabs here). If that all doesn't do it, it must be related to usbcore. My modules.dep has: /lib/modules/2.6.3-mph1/kernel/sound/usb/snd-usb-audio.ko: /lib/modules/2.6.3-mph1/kernel/drivers/usb/core/usbcore.ko /lib/modules/2.6.3-mph1/kernel/sound/core/snd-rawmidi.ko /lib/modules/2.6.3-mph1/kernel/sound/core/seq/snd-seq-device.ko /lib/modules/2.6.3-mph1/kernel/sound/core/snd-pcm.ko /lib/modules/2.6.3-mph1/kernel/sound/core/snd-page-alloc.ko /lib/modules/2.6.3-mph1/kernel/sound/core/snd-timer.ko But that could very well be different in 2.4.
