Raspberry Pi Zero W not connecting to digirig

1

I am trying to setup direwolf on a raspberry pi zero w with my digirig. I have direwolf all installed and i also installed ALSA on the pi. When configuring direwolf i need to give it a soundcard number of the digirig and usually this is done using the “aplay -l” command. It appears that the digirig is being recognized as a USB device but it is not being assigned a sound card number. Has anyone seen this and if so how did you fix it?

When i run that command it returns the following

aplay: device_list:274: no soundcards found…

so i used the lsusb command and found the following

Bus 001 Device 004: ID 10c4:ea60 Silicon Labs CP210x UART Bridge
Bus 001 Device 003: ID 0d8:c:013c C-Media Electronics, Inc. CM108 Audio Controller
Bus001 Device 002: ID 0424:2412 Microchip Technology, Inc. (formerly SMSC) Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Maybe this will help some people, I used OTG Hub https://www.amazon.com/dp/B09XK36QNB and the Digirig Lite would not be seen at all. I tested the mobile version and that does work. So I moved the digirig Lite to a second hub connected to the OTG hub and then it does get recognized.
Then it wont write to the audio Errors… major frustration.

I unplugged the OTG hub. plugged the digirig lite into the hub direct and then plugged it all back into the Pi zero 2w and it finally works.

Thanks for the info. This is not optimal arrangement.
I’ll give that a try with my Pi Zero later and see if I can reproduce the issue.

I tried a different OTG hub and I downgraded to 32bit raspian os. seams to be working better now.
