From: Paul EggletonI apologize for my ignorance, but I really don't know how to go about
figuring this out.
There is a file called /lib/udev/rules.d/60-persistent-alsa.rules, which is
full of cryptic stuff that I don't understand, including two lines referring
to usb, but nothing specifically about MIDI. I compared it to the file on
Ubuntu, and it's similar but not the same, but I have no idea whether any of
the differences are meaningful. They're both small, so I've attached them.
Also, I see that while the alsa-utils recipe is being built, the resulting
image only seems to have a couple of alsa utilities: alsamixer and alsactl,
even though there are a whole lot more listed in
And when I run the system, there is no /dev/snd/seq device, which is the
main interface to all MIDI devices. I don't plan on using that, preferring
to use the /dev/snd/midi* OSS emulation device which is supposed to appear
when an individual device is connected, but that's not happening, either.
How do I find out if USB MIDI support is enabled in the kernel?
This is plain vanilla core-image-base-cedartrail-nopvr, without any
modifications. ALSA is part of it. Isn't it supposed to just work?
