I tried that workaround and it didn't work.

$ gphoto2 --camera "Canon Powershot S1 IS (PTP mode)" --port=usb\: -L

*** Error ***              
An error occurred in the io-library ('Bad parameters'): Could not find USB device (vendor 0x4a9, product 0x309c). Make sure this device is connected to the computer.
*** Error (-2: 'Bad parameters') ***       

For debugging messages, please use the --debug option.
Debugging messages may help finding a solution to your problem.
If you intend to send any error or debug messages to the gphoto
developer mailing list <gphoto-devel@lists.sourceforge.net>, please run
gphoto2 as follows:

    env LANG=C gphoto2 --debug --camera "Canon Powershot S1 IS (PTP mode)" --port=usb: -L

Please make sure there is sufficient quoting around the arguments.

At least the person in the bug report had their camera detected, so I
know I should at least be able to get that far. It's also what makes
me think that I have a problem with my configuration, and it might be
Debian specific.

I might well end up doing that. It also reduces the risk that I catch
the wire and send my camera plummeting to the floor.
