This is pure guesswork.
For Canon (and most other) cameras, there are no kernel modules as gphoto2
uses the userland libusb. It's possible that your hotplug configuration is
not setting the device to have the correct permissions. You might try the
suggestions in:
http://www.tappin.me.uk/Linux/user-hotplug.html
Substituting the relevant device ID in place of that for the S20.
The other possibility is that the devusb filesystem is not enabled --
anybody know if stock Debian kernels enable it?.
