My Raspberry Pi 4b doesn’t recognize my digirig lite at all, using lsusb or the detection system in the Graywolf APRS app. I have the stock 64-bit Linux OS freshly loaded and updated on the Raspberry Pi. When plugged in my Linux laptop it shows up as a C-Media device.

There were earlier reports with Raspberry Pi occasionally failing to detect otherwise working Digirig Lite. This doesn’t happen with Digirig Mobile likely because it has an internal USB hub and can condition the signals. Using something like USB isolator can have the same effect. Alternatively, I’m …

As shown in most of the most popular YiuTube videos that showing the setup of Graywolf, your Pi will show the Digirig lite as: C-Media Drive. Check out the most current video from Jason - KM4ACK…it is a great tutorial on setting up Graywolf with a Raspberry Pi 73, Danny NF4J

I just located a USB Isolator that I had - that solved the problem. Thanks! Ooops! Spoke too quickly. It shows Input and Output but not cm108 PTT, or any other PTT … sigh.

There is no PTT device separate from CM108. With Digirig Lite the PTT method is implemented in the audio codec: GPIO3 or VOX.

I looked more closely at the Graywolf instructions and say that PTT settings weren’t linked from the Audio Devices page. I went there and tried things, but no PTT. Their instructions say: “Recommended for PTT — the best match for your hardware (e.g. an AIOC or Digirig adapter showing as cm108 on /de…

yes, you must match your ptt device to the number/name/identifier that your os shows for the digirig. good luck kb0wlf

Graywolf appears to want a cm108 on /dev/hidraw1 but the digirig lite is showing up as a hidraw4. I don’t see any way to change that. Do you know how, please? I just looked in /dev/ and see that hidraw1, 2, 3, and 4 are all available. Is there a way that I can force the digirig lite to use hidraw …

Yesterday the digirig lite showed as hidraw4, today it was hidraw3, I deleted things and rebooted and now it’s showing as hidraw0. (As I understand Graywolf it needs to be hidraw1.) Maybe if I keep deleting and rebooting I might catch it at hidraw1 - but then I don’t know if that will hold through t…

Digirig lite not recognized on Raspberry Pi & is on my Linux laptop

i don’t use graywolf but i cant imagine the author hard coded the device id.
there ought to be a selection ‘box’ somewhere to set which device you want

perhaps @NW5W can jump in and explain
