I am having issues getting ptt to work.I added a usb c hub with no change. I am using an ft 60r with a cable purchased from digirig and android aprs app.
I have changed usb routing and made sure the app has permisions to access the microphone.
Were you able to key up the radio while using Digirig Lite on the full-size computer?
You can also test the cable by simulating the PTT as demonstrated in this video:
I havent tried using a laptop yet.
