newer cameras have multiple usb operation modes (MTP, PTP etc.). Are you
sure you read the documentation around this? Also on my simple camera I
have one port for charging and one for data transfer. The second is not a
different USB cable.
according https://ubuntuforums.org/showthread.php?t=2367467 transfer is
possible. Could be your kernel is too old?

Did you read this

and make sure you have the drivers?
