Why can't I connect to my GoPro to my in Gentoo Linux?

I want to download the files from my GoPro Hero5 Session, but I can't mount it to my laptop. When I connect the camera, the logs detect a new device (pasted below), but nothing appears in /dev/sd*, so I can't even try to mount it manually. I have FUSE enabled in kernel (for example sshfs works), and exfat-utils and fuse-exfat installed. What can I do to debug this further?

I can connect to the GoPro's wifi, but I still want to be able to mount int normally for faster transfer.

The GoPro is fully updated. Running gentoo with kernel 4.10.1. Logs from connecting the camera:

I managed to connect to the camera using gphoto2 from terminal, and also using gphotofs to browse the files.

I probably was wrong thinking it should appear in /dev/sd* in the first place, maybe that was true for some other models. This camera must use another protocol.
