can't connect to phone for file transfer since update

English Install/Boot/Login
1

Last week I updated from 20210611 to 20210708
Since that time I no longer get device connection notifications.
Loading the previous snapshot (20210611) all works as it should.

So, in the latest update what I see is . . .
Connect phone via usb to computer
system tray pops up showing phone connected but not accessible (this is normal behaviour)
Go to the phone (android 10) and change from “usb charging” to “file transfer”
In previous snapshot this will prompt system tray to pop up with a request to mount / open
However, in the current version all I see is “no removable devices attached”

But . . . in dolphin I can see the device listed as removable storage and can access as usual.
Any idea what is going on here?

Any help greatly appreciated

KDE? Then possibly related to this bug: https://bugs.kde.org/show_bug.cgi?id=438874

thanks, yes.
Also found this thread which is surely the same problem

Device notifier is great again with 20210713.

Indeed it is.

Not here it’s not … :frowning:

Just updated two TW systems to 20210714 and I’m still seeing the same behavior. Device notifier is triggered only on the first insertion of the device…

Upgraded and tried again. Journal starts with error.

Device notifier reliably works with all 6 sticks available.

Following an insert/mount/unmount/remove does it the trigger the device manager if the usb-stick is inserted a second time? Here it always works the first time following either login (to kde) or a restart of plasma shell, but fails on the second attempt.

I’ve also seen a report 439412 – Disks & Devices applet says "No removable devices attached" even when a CD/DVD/BD disc is mounted where CD/DVD/BD disk insertion is failing to trigger the device manager, and I can not help but wonder if there is a common underlying cause.

9

Good point! Inserted the same USB-stick again, didn’t show up again on the Desktop! But I see it in Dolphin.

I had recognized that some days ago, but didn’t have the time to follow-up…

10

Thanks for confirming that :slight_smile: … Yeah it’s this bug: 438874 – Disk & Devices applet doesn't show USB removable devices and SD cards after disconnecting and re-connecting them

As you wrote it appears in Dolphin, and also in “System Settings -> Removable Storage -> Removable Devices” , but Device Manager is unaware of it… Hopefully it will be fixed fairly soon, for the moment I’ve been using Dolphin to mount/unmount devices.

11

Strange as to why it works on your system… :\

I wonder if it’s hardware dependent in some way, although others are seeing this, there doesn’t appear to be a flood of bug reports about it, so perhaps it’s not a widespread bug.
