However hal in some way cooperates with gphoto2 database of cameras as far as I
understand. Right now gphoto2 advertises S1 in both normal and ptp mode. The
first one is automatically chosen. Maybe if it was somehow deleted from the list
of supported cameras it will initialize camera in ptp mode?

I can force ptp in two ways:

1. using gphoto with following command:
gphoto2 --camera "Canon Powershot S1 IS (PTP mode)" --port usb: --additional-options

2. I launch gthumb _before_ camera is connected and I click on "Import Photos".
The camera abviously cannot be found and gthumb allows user to choose camera
manually. I chose S1 in ptp mode and connect camera.
