Logitech QuickCam Pro 9000

Windows
After installation, the software that comes with the camera works well and can capture HD-like video very well. However, when using a third party capture application, size seems to be stuck at 320x240 pixels. Holy crap!

Linux

 * Camera detected and mounted as /dev/video0
 * Most apps are completely dysfunctional and useless (as usual)
 * uvccapture works fine
 * width and height: OK
 * Brightness: TBD

 * Gain: TBD
 * Supported image sizes: TBD
 * guvcview works! and has many interesting controls
 * Can capture video
 * Can capture audio
 * No focus control

Autofocus
Autofocus is built into the wintendo drives, thus does not work in Linux.

How can we manually control focus in Linux?
