I just finished setting up the FP5 and tried to transfer some files via USB.
The connection is there, I can go to the connection options where you should be able to select charging, file transfer etc but these options are greyed out.
I tried various USB-A to C cables that definitively work on the FP4 and many other devices that require USB-C 3.1 cables without success.
Using a card reader on the USB port works so data transfer is absolutely possible.
Does anybody have the same issue and maybe a solution for this?
