hi,

both cheese and ekiga does not work with my syneus (174f:5931) webcam while 
luvcview works fine.

linux is v2.6.29-rc8-124-g5bee17f, libv4l is 0.5.9 on debian sid.

This is what cheese -v says:

Cheese 2.24.3

libv4l2: error setting pixformat: Device or resource busy
libv4l2: error requesting 4 buffers: Device or resource busy

I've already asked on uvc devel and Laurent comes to this conclusion after 
looking at the driver logs you'll find attached:

That's definitely the problem. After calling VIDIOC_STREAMOFF to stop
streaming, cheese doesn't close the device and opens another instance. This 
is likely a bug in cheese or libv4l2.

thanks.
