can't mount android device

[cadvanlei]

hello there,

I'm running Kubuntu 16.04 on an Asus ZenBook UX301LA (please see below). I also have two android devices (Asus ZenPad + Asus ZenFone).

when I connect either device, Dolphin shows the following message:

The process for the mtp protocol died unexpectedly.

(occasionally the message is slightly different: Could not read. Reason: Could not claim the USB device).

I found a few posts about having to install kio-mtp (which - according to Synaptics - is already installed: version 0.75 + git 20140304) but no other hint there might be a different solution.

can you please help? thanks.

here're some info about my system (what I could gather):

I tried switching to USB>PTP (instead of MTP) on my android device: I can read but cannot transfer files Kubuntu>Android.

[cadvanlei]

update: reboot + connect android device again. This time I get the following error:

The file or folder udi=/org/kde/solid/udev/sys/devices/pci0000:00/0000:00:14.0/usb1/1-2/ does not exist.

after switching back to MTP mode on the android device, that is

On my desktop MTP android transfer will not work or fails part way through, no matter what I try.

On my laptop it works flawlessly with same config.

MTP is inherently dodgy, perhaps partly because it's a Microsoft protocol. Have you tried using KDE Connect? One end already in your Xenial, the other free in Google play.
