I don't expect a PTP device is mounted as mass storage, but I do expect
Dolphin can read its contents, using whatever method it chooses to access
the device. Instead, it only shows "Loading folder" forever and never
finishes reading.
I don't use Digikam, I only want to copy files. This is a task that should
be done by a file manager.
But this is not a very important issue to me, I have a card reader attached
to the computer and it is quicker to use it to read the sd card than
finding the cable to connect the camera.
