Plasma 5.24.7, Ubuntu Studio 22.04.
My Android tablet that I use as a performance controller was a bit low on battery, so I plugged it into an open port on my USB hub and selected "charge only"...
... whereupon Plasma's otherwise very useful Disks & Devices indicator proceeded to try to mount the tablet as a media storage device. This failed (because the device was set to charge only)... whereupon Plasma tried again, and it failed again... and it tried again, and it failed again... and it tried again, and it failed again...
At which point, I realized that the action of charging a device from a USB port conflicts with Plasma's aggressiveness in automounting any devices it sees. Not supported in this shell.
I then changed system settings to disable all automount options... and Plasma still insisted on trying to mount.
So how do I disable this behavior?
