My Nikon Z6iii is not recognized as a block device when connecting via USB.
This is how it shows up in the Disks & Devices widget:
This is the output from journalctl (I removed the date and the hostname for clarity):

It seems that the log messages “device: 7 was not an MTP device” and “is not a StorageAccess device” hint at the problem.
I have double-checked that the USB setting in the camera’s Network menu is set to “MTP/PTP”.
Since there are two devices initially being recognized, I tried it with just one of the memory cards in the camera, but regardless whether the CFexpress card or the SD card is in the camera, the block device is not recognized.
When I start up Windows in a VirtualBox machine and pass through the camera into the VM, I can connect and access both cards as separate devices.
Does anybody know why my Linux machine chokes on this USB connection?

Thanks.
