From personal experience and research, I think that the LifeCam doesn't preserve its settings after a power cycle, and, because you can't configure the settings from the RIO, it makes it difficult to have a configured camera on a robot. Usually. Some people, probably including you, wt200999, seem to have LifeCams that just work. They preserve their settings after a power cycle where other LifeCams would not. After hours of digging through Google search results, I haven't found the reason why.
Its more erratic than that. I conducted several trials today:
1. Restarted robot code from dashboard - Settings lost
2. Reset settings, power cycled robot, loaded new code - Settings lost
3. Reset settings, plugged back into rio without power cycle - settings lost
4. Did not reset settings, restarted rio from dashboard - settings worked (note, these were settings from before trial 3 that didn't show after trial 3)
5. Restart robot code from dashboard - settings worked
6. Restart RIO from button on rio - settings worked
7. Load new code - settings worked
8. Hard power cycle (turn power switch off/on) - settings worked

If anyone has example code using USBCamera successfully, it would be greatly appreciated.
