Erik, Jason and all,
Yes, it looks like upgrading to the new kernel might have solved my
problems!!
I did this:
sudo apt-get update
sudo apt-get install linux-image-4.1.12-bone16
[reboot!!]
debian@vBBB9-Office-Cl4:~$ uname -a
Linux vBBB9-Office-Cl4 4.1.12-bone16 #1 Wed Oct 28 07:32:53 UTC 2015 armv7l
GNU/Linux
debian@vBBB9-Office-Cl4:~$ lsusb
Bus 001 Device 002: ID 1a86:752d QinHeng Electronics CH345 MIDI adapter
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
debian@vBBB9-Office-Cl4:~$ aconnect -i
client 0: 'System' [type=kernel]
0 'Timer '
1 'Announce '
client 14: 'Midi Through' [type=kernel]
0 'Midi Through Port-0'
client 16: 'USB2.0-MIDI' [type=kernel]
0 'USB2.0-MIDI MIDI 1'
This looks much better!!! I will try to access the midi stuff from Python
sometime next week.
Erik, let me know if this helps with your situation with SuperCollider.
PS-Mr. Hermans, why do you use an rt kernel?
talk soon and thanks!
