How to recognize USB audio device when plugged in

Postby drmacro » 2020-03-07 14:54

When I plug in my USB audio device on UbuntuStudio, lsusb knows it's manufacturer, etc. and it's audio ports are automagically added to, for example, JACK audio devices.
(I never loaded a device driver, etc. on UBS, so I'm assuming they add something. The ID doesn't show in the Debian device lists on the web, so again, something is added by UBS...I guess?)

When I plug in to Debian10, it's USB ID shows up with lsusb, but it is not recognized and no audio I/O is added.

I realize UBS does magic behind the scenes, but, I'd like to duplicate that magic.

Are there any guides or ideas on the path to getting this working?

Is it a new device? Debian buster's kernel is over a year old now so it might not support it.

What are the actual outputs from your various commands? And why do people like you take the time to describe output (vaguely) rather than just copy&paste it? That confuses and irritates me.

Thanks for the reply. Sorry my laziness is the only excuse...had to sneaker net it from the other PC. The ID 22f0:0014 on the non-working one is the ZEDi8 mixer.

It's a moot issue at this point because after I rebooted a couple times (for other reasons) it is now seems to be ok, but the ID 22f0:0014 is still as shown below, with no info from the lsusb.

It's been in use with other Debian based (UbuntuStudio, AVLinux) OS's for quite sometime. So I don't think it's that new.

Output from the working PC (UbuntuStudio)

Code: Select all
lsusb
Bus 001 Device 006: ID 22f0:0014 Allen & Heath ZEDi8


Code: Select all
cat /proc/asound/cards

                      HDA Intel PCH at 0xda120000 irq 130

From the previously not working PC:
