Hello! I have an Samsung S23+ who’s MTP not detected on Dolphin with message (No MTP-compatible devices found).
Meanwhile, with current KDE LIVE CD detected, i browser the phone from Network / MTP Devices.
Perhaps i am missing a package, lib or configuration somewhere?
$ mtp-detect

For information
When i have installed my tumbleweed, from Security i disabled ssh and blocked open port. I don’t know if stopping those prevent MTP to function properly?
Details
Operating System: openSUSE Tumbleweed 20250316
KDE Plasma Version: 6.3.3
KDE Frameworks Version: 6.11.0
Qt Version: 6.8.2
Graphics Platform: Wayland
Unlike to most users there, i have no connection signs or popup at all on my KDE, Dolphin, or System Tray.
Even this popup doesn’t appear on my phone when i plug USB-C cable. Only i hear the notification sound which heard when a USB connection is made.
Before opening my bug ticket it was working for a year or so. Somewhere around September, October of last year it stopped working. I report it as a bug, but i noticed that others had some sort of signs of working somewhere. And I didn’t, then from February of this year I did a new installation, minimal from netinst and again the same situation.
Okay, let say it’s a bug as i and some others have reported, been confirmed as status on ticket says “CONFIRMED”, However, Live CD with the same Tumbleweed snapshot 20250316 - phone, popup, MTP Devices all detected and works.
I’m convinced that something is missing on my system regardless of whether the bug exists.
I had the same issue some weeks ago. Long story short: it was a broken USB cable. Charging was still possible but no data transfer. A new cable solved all issues.
You have libmtp-udev and libmtp9 in both package lists as expected. You have kio-fuse in the “LIVE CD” list, although from what I understand that shouldn’t be required from a KIO perspective. It provides a daemon which makes KIO URLs accessible to KIO unaware applications using FUSE.
Do both produce the same output when the mobile phone is first attached? udevadm monitor
Thanks for your reply, installed kio-fuse made a system reboot. Went back on Dolphin > Network > MTP Devices. Still No MTP-compatible devices found. Installing kio-fuse hadn’t changed anything.
Thanks for your advice, Well, it’s easier for me with MTP, file manager and go directly to the phone’s files. The transfer is fast from both sides.
KDE Connect i find the right click on a file send to Phone very comfortable, practical and fast too.
But in some other app settings, I also encounter issues such as crashes or not recognizing the mobile system phone. Maybe there’s a bug i’ve encountered, but i’m not ready for this yet.
I mentioned that it is not required here - it’s only used to create a virtual file system so that other applications can work with the MTP device in this case.
Some users have reported success if they make sure that all Dolphin instances are closed while connecting the Samsung mobile device. Do you observe any difference in behaviour?
Reading the open KDE bug report you linked to earlier, comment #10 mentions using the solid-hardware6 command to gain a better understanding of what might be occurring… https://bugs.kde.org/show_bug.cgi?id=497539#c10
Maybe your best path forward is to subscribe to one of these bug reports (if using MTP is your preferred file transfer option).
I have read on the kio-extras bug comments and i made sure that dolphin is completely closed, but had no success either closed or open.
Have read the comment #10, but what do i miss about solid-hardware6solid-tools ?
bash: solid-hardware6: command not found
Thanks for the bug links, those and a few others i follow systematically, I see a lot of Tumbleweed reporting, hope in a fix on the upcoming updates since it’s been a few months now.
