Gphoto2 missing USB support

installed gphoto2 snap on Raspberry 2 B
Camera connected through USB - Canon PowerShot 5G (this is a pretty old model)
After installation and reboot run gphoto2 --list-ports
only see 2 ports - serial and ptp, no USB ports is visible.
Camera is not auto-detected.
Removed gphoto2 with ‘snap remove gphoto2’
Re-installed with
‘sudo apt install gphoto2’
run gphoto2 --list-ports again
now it shows usb port available and camera is detected.
