In that case loading the source manually fails, because the device is
already open, unless you load the source before module-hal-detect. I
don't think module-hal-detect will cause a fatal error if it fails to
open an already opened device, so this should be a satisfactory
workaround. The correct fix would of course be to fix the webcam drivers
- if only some sample rates work, opening the device with anything else
should fail.

When the startup fails, pasting the error messages would be helpful.
