I'm unable to connect to the watch using USB in any way. I want to transfer some music files from my library. This used to work just fine, but now I simply can't get any connection at all. I've tried on my Kubuntu system, on an Android phone (using the USB cable) and on a Windows 11 laptop. None of these are working. I've also tried Garmin Express, but it doesn't detect the watch at all. It seems the watch is trying to setup a data connection, but aborts after a few seconds. The windows 11 laptop kept giving the audio feedback of a USB device being connected and disconnected over and over again.
Is this a problem with the 15.16 software update? I've managed to transfer music files to my watch when a bought it, but now it's not working anymore.
