Pan/tilt support is implemented but requires the help of the uvcdynctrl application to configure the driver. Pan/tilt is implemented as proprietary (but documented) controls on Logitech webcams. The driver needs to be configured at runtime with additional information to access those controls. Please install the uvcdynctrl application (part of libwebcam) to configure the driver. libwebcam can be downloaded from http://www.quickcamteam.net/software/libwebcam. Make sure you get the latest version from the SVN repository as the 0.1.1 package is outdated. Control settings are not permanent so you will need to run uvcdynctrl each time you load the driver. This can be automated through udev/hal (libwebcam includes helper scripts). > Is this a feature that is not going to be implemented? > > What might a progamming layman like myself do to assist in getting > this feature implemented? > > Below is the output of 'lsusb -d 046d:0994 -v'. > > Thank you very much for all the work you have done on uvc. You're welcome.
