Describe the bug

I did look through the issues and https://github.com/gphoto/libgphoto2/issues/343 seems to indicate that my camera should be supported but I can't do anything at all. I suspect it's me doing something wrong but I can't figure it out by myself.

I tried importing images using Digikam 7.6.0 but it failed. Then I tried just listing directories by using gphoto2 --list-folders

Name the camera Camera name as shown by gphoto2 --auto-detect or USB IDs

I see that Ubuntu ships /usr/lib/udev/hwdb.d/20-libgphoto2-6.hwdb which has the following entries

# Sony Alpha-A7 III (MTP mode)
usb:v054Cp0C03*   
 GPHOTO2_DRIVER=PTP
 ID_GPHOTO2=1

# Sony Alpha-A7 III (PC Control)
usb:v054Cp0C34*    
 GPHOTO2_DRIVER=PTP
 ID_GPHOTO2=1

However, none of these seem to match 054c:0c01 which my camera is using :thinking:

A-ha, I had to change USB Connection to MTP in the camera settings. Now I can discover it via gphoto2 --auto-detect. BUT I still can't transfer anything because it fails with PTP I/O Error when listing folders.

I'll open a separate issue for that, though.
