I hope to find a better fix with Logitech's help. In the meantime, you can apply it. > The camera works OK if I run uvccapture in -t 1 mode (ie, continious > shots).

The UVC driver already supports pan/tilt through a special control, but that will change soon with a new generic IOCTL. I'm working on that, stay tuned :-) > 3.
