Yes, I see exactly as how you describe,  almost, note yours is using ehci,
mine uses uhci

usb 4-2: new full speed USB device using uhci_hcd and address 2
usb 4-2: configuration #1 chosen from 1 choice


and I only see one mountpoint,
~/.gvfs$ ls
gphoto2 mount on usb%3A004,002

and
usb 4-2: USB disconnect, address 2

so I'm at a loss as to why it pops up multiple times, tried all 3 USB ports
(laptop) same with them, removed mains, and disabled wireless with no
difference.

Thanks
