Hi Daniel, IMHO the 0.2.1 luvcview version does not support dynamic controls, which the newest linux-uvc driver version provides. That is the reason for the querycontrol 22 errors.
Please download libwebcam from ... http://www.quickcamteam.net/software/libwebcam ... and set the controls via uvcdynctrl manually. The controls will retain the same setting as long as the cam is plugged in and will then revert to default settings. So, setting the controls, then testing if it works via luvcview should work. I tested the software autofocus in a similar setting. Also, if you need this in your own application, take a look at my autofocus code at http://projects.seewald.at .... it shows how to work with both old driver (static controls) and new driver (dynamic controls), setting up the focus control on-the-fly if necessary, but using a preconfigured control (by uvcdynctrl) as well.
