Getting USB MIDI devices to work

Hello everyone,

I am desperately trying to get an KORG nano key to work under Arch Linux. It used to be plug an play for all I remember but something must have changed. The device shows up correctly when using 'lsusb':

Bus 002 Device 006: ID 0944:010d KORG, Inc. nanoKEY MIDI keyboard

But checking for available MIDI devices via 'aconnect -i' just yields:

Client 0: 'System' [Typ=Kernel]
    0 'Timer           '
    1 'Announce        '
Client 14: 'Midi Through' [Typ=Kernel]
    0 'Midi Through Port-0'

Following the USB MIDI Keyboard article in the wiki I checked for the 'usb_midi' module to be loaded. 'lsmod | grep usb' yields:

snd_usb_audio         149328  0 
snd_usbmidi_lib        27571  1 snd_usb_audio
snd_rawmidi            26806  1 snd_usbmidi_lib
snd_hwdep              17244  2 snd_usb_audio,snd_hda_codec
snd_pcm                88779  7 snd_usb_audio,snd_hda_codec_hdmi,snd_hda_codec,snd_hda_intel,snd_hda_controller
snd                    73436  37 snd_hda_codec_realtek,snd_usb_audio,snd_hwdep,snd_timer,snd_hda_codec_hdmi,snd_pcm,snd_seq,snd_rawmidi,snd_hda_codec_generic,snd_usbmidi_lib,snd_hda_codec,snd_hda_intel,snd_seq_device
usbhid                 48596  0 
hid                   110513  3 hid_cherry,hid_generic,usbhid
usbcore               199382  7 snd_usb_audio,snd_usbmidi_lib,ehci_hcd,ehci_pci usbhid,xhci_hcd,xhci_pci
usb_common             12561  1 usbcore

Clearly I am missing something...

Every bit bit of help is appreciated.

Re: Getting USB MIDI devices to work

do you need the extra/alsa-firmware package, I need it for my audio interface so i install it on any system i plan on using for music production, not sure if my midi interfaces depend on it.

Re: Getting USB MIDI devices to work

It's a regression in 3.19.2, either downgrade to 3.19.1 or wait for an update

That was indeed the case. Thank you very much. For a second I felt quite stupid here.

Re: Getting USB MIDI devices to work

You can see the bug report here, but this is fixed for me with 3.19.3 from [testing].
