SUMMARY

My Pixel 2 XL shows up in Disks & Devices after accessing it from the Places view in Dolphin. It used to appear automatically after plugging in. This is a high-speed (USB 2) device.

My Pixel 5 does not show up in Disks & Devices in any case. I am plugging it in via a Thunderbolt bridged connector just in case this makes a difference. This allows the device to use SuperSpeed without going through a USB-A connector.

Browsing from Dolphin works fine. I think Pixel devices or any MTP device should be appearing under Removable Devices, but both show up in the 'Devices' section in the Places view.

STEPS TO REPRODUCE
1. Have a Plasma Panel configured to show a System Tray widget with Disks & Devices
2. Plug in an MTP device

OBSERVED RESULT

Disks & Devices does not show a new device.

EXPECTED RESULT

Disks & Devices should show the new device.

Hmm, it's supposed to. My phone shows up in there FWIW.

Comment 2 Andrew Udvare 2021-09-21 21:20:01 UTC

It's an issue that seems to be intermittent.

If this happens again, what kind of information can I attach for debugging?

Comment 3 Nate Graham 2021-09-21 23:38:57 UTC

I don't know, sorry.

In case it only fails to appear if you plug it in a second time after having had ejected it, then this is another duplicate of bug 438874, supposedly fixed by kde-plasma/plasma-workspace-5.22.5-r2.

Comment 5 Andrew Udvare 2021-09-26 01:51:33 UTC

Honestly I think this is a USB-C cable issue. Sometimes the cable works, other times it doesn't. If I use a USB-C to 3.x cable, it always works.

That can happen, yeah! Glad you got it figured out.
