I've had a USB Oxygen61 MIDI keyboard for awhile now, and it has worked fine in the past (maybe a month ago, last I tried). But now when I plug it in, it no longer shows up in aconnect -l, and I can't see it as an ALSA MIDI device in Jack.

It powers up and dmesg reports this:

usb 11-2: new full-speed USB device number 7 using ohci-pci

I can see it listed in lsusb like this:

Bus 009 Device 003: ID 0763:2028 Midiman

Output of amidi -l:

 3 [O61            ]: USB-Audio - Oxygen 61
                      M-Audio Oxygen 61 at usb-0000:00:13.0-1, full speed

Where should I start to troubleshoot why this device is not listed in qjackctl as an ALSA device?

  • Does it show up in the output of `amidi -l` and `cat /proc/asound/cards`? What is the difference between "now" and previously? – CL. May 02 '15 at 06:23
  • Adding amidi -l outputs, modifying the question – davex_ May 02 '15 at 13:33

    Does `snd-seq-midi` show up in the output of `lsmod`? If not, does `modprobe snd-seq-midi` help? – CL. May 02 '15 at 15:04
  • There we go. After running modprobe snd-seq-midi, now I can see Oxygen-61 listed in aconnect -l output. Strange that this module was not loading anymore. – davex_ May 02 '15 at 15:16
  • Apparently, your distribution (whatever it is) broke module loading with some update. File a bug. – CL. May 02 '15 at 20:51
