I've read conflicting reports in the archives as to whether my Canon camera should work. I've also read conflicting reports about additional files needed to make USB control truly functional.

What else should I try to get USB control working with my Canon camera?

After the failed host mode test, I used USB control to put the N810 back in peripheral mode. But I had to restart the N810 multiple times before the unit actually went back into peripheral mode (that is, before my PC could see the N810's memory). Is USB control really that gawd-awful?
Sorry to disappoint you, but... that's not a failed host-mode test, that's a successful host-mode test. The first message always shows up, as a friendly warning. The second one shows up when a device that's neither HID nor mass-storage is detected. Unfortunately, 30 seconds with Google turned up statements that the SD800 "uses PTP and MTP, but not USB mass storage", so you'll need to use some program that speaks one of those (maybe gphoto2, or some other libgphoto-based software) rather than the file manager.

Not sure about returning to normal mode, unless your camera tried to draw too much current, in which case the port may shutdown entirely until reboot.
