Title: USB Midi Devices
Post by: DeepBlueMind on August 03, 2021, 03:39:50 AM

Hello again,

I have two USB Midi devices connected via USB hub and when I do this command:

aconnect -l

they don't show up!

What do I miss?

If you disconnect and re-connect your usb devices and then "dmesg | tail -20", does your machine recognise that something has been connected?

You could try to install usbutils.tcz and then run lsusb to get more info about the devices.

a "aconnect -l" command gives me this:

client 0: 'System' [type=kernel]

    0 'Timer           '

    1 'Announce        '

client 14: 'Midi Through' [type=kernel]

    0 'Midi Through Port-0'

the lsusb command gives this:

Bus 001 Device 009: ID 1fc9:8260 NXP Semiconductors

Bus 001 Device 003: ID 045e:0752 Microsoft Corp. Wired Keyboard 400

Bus 001 Device 002: ID 1a40:0101 Terminus Technology Inc. Hub

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

so the first device is being recognized but not the second USB Midi Device, but it is not shown on the "aconnect -l" command

Nothing changes only when I disconnect one USB Midi device and then "dmesg | tail -20" I got this:
[ 1226.933052] usb 1-1.3: USB disconnect, device number 11
and the same with the other one I got this:
[ 1368.249413] usb 1-1.2: USB disconnect, device number 8
