Passed through webcam has extremely poor resolution

[gquipster]

Hi,

I'm running Virtual Box 4.3.4r91027 with latest extension pack passing through a Logitech webcam from Ubuntu 12.04LTS host to Windows 7 64-bit Professional guest running 4.3.4r91027 guest additions.

On Ubuntu if I run Cheese then the image is good quality 640x480 resolutiuon. On Windows I get a resolution of 160x120 and a really blocky image.

The driver being used in Windows is a "Microsoft USB Video" driver version 6.1.7601.18208 from 21/06/2006. I cannot find any control panel where I can change the resolution or brightness/contrast levels etc. Also even if I change the driver to a logitech driver then the camera is not recognised by the Logitech webcam software,

Please can you advise as it's making video conferencing very difficult.

Please attach VBox.log of a session where you get the 160x120 image in the windows guest.

Which application do you use in the Windows guest with the webcam?

Used a different driver (QuickCam Pro 3000 instead of QuickCam Pro 5000 which the camera actually is) and quality is now vastly improved.

Thanks anyway.
