Anecdotal ...
You can plug in (and turn on) a camera and get a notification that there's a
new device. You click on the "mount" and not see anything appear in the Dolphin
side panel . You can type "camera:" into the location bar and see the file
folders. That's worked for me in most cases...
I've fallen into a couple of "Traps for the Unwary" though:
If you turn off the camera and immediately turn it back on again, dolphin
shows:
Unknown error code 150
Bad parameters
Please send a full bug report at https://bugs.kde.org
This is probably the result of Dolphin caching results and not seeing that the
camera has "gone" and reappeared somewhere else. When I look with "dmesg" I see
that originally it gave:
usb 2-3: new high-speed USB device number 3 using ehci-pci
and turning the camera off and back on again gave:
usb 2-3: new high-speed USB device number 4 using ehci-pci
I don't get a KDE notification and I don't see the camera in the Discs &
Devices. If I close Dolphin and relaunch, the error goes but I get empty
"camera:" folders. The solution was to reboot the VM. Note that my experiments
are done in a KVM guest system, Fedora 38. Behaviour on a native install may
differ.
Second trap was when the Camera battery was "low" (and I had not noticed).
This lead to the situation that I could plug the camera in and get the
notification (and see dmsg reporting the New USB device found) but not being
able to see the camera's file folders even when typing "camera:" in the
location bar.
I will flag this as anecdotal and suspect, when I charged the camera battery
all went well again. Therefore not really something I could go back and test
but a hint perhaps for the similarly confused...
