In "mass storage" mode, a normal USB-backed da device should appear (this is not the default for smartphones). Until all involved stages of the device connection have been secured, no da device will be accessible for tasks like mounting. > DMESG shows only device connected and disconnected in a loop..

This should not matter. Especially for PTP ("media transfer" modes) a normal ugen device usually is sufficient. > Any hints appreciated :-) Check both the cable and the USB port on the computer. Judging from your description, a connect/disconnect loop suggests a connection problem. Also make sure your cable is compatible (!) with both your device and your computer. Backwards Compatability. The physical USB-C connector isn't backwards compatible, but the underlying USB standard is. You can't plug older USB devices into a modern, tiny USB-C port, nor can you connect a USB-C connector into an older, larger USB port. But that doesn't mean you have to discard all your old peripherals.
