MTP device does not show up when plugged in (KDE, Debian 12)

[ermonnezza]

Hello all,

I never managed to use my phone as a device in Strawberry. It does not show up in the Devices pane when plugged in. It is not auto-mounted, but I can access it and transfer files from/to using a file browser, via MTP. However I need to do that in Strawberry, as I have lots of lossless music I would like to transcode on the fly when copying it to the phone.

Here is the system I am currently using:

Operating System: Debian GNU/Linux 12
KDE Plasma Version: 5.27.5
KDE Frameworks Version: 5.103.0
Qt Version: 5.15.8
Kernel Version: 6.1.0-52-amd64 (64-bit)
Graphics Platform: X11
Processors: 4 × Intel Pentium CPU G4600 @ 3.60GHz
Memory: 15.5 GiB of RAM
Graphics Processor: Mesa Intel HD Graphics 630

Strawberry version: 1.0.14

I tried to launch strawberry --verbose in a shell and plug the phone in, but nothing shows up as a message.

Here's the output of dmesg when I plug it in:

[14412.899821] usb 3-1: new high-speed USB device number 16 using xhci_hcd

Any hint for debugging this? Thanks a lot..
