That definitely sounds like a camera bug, but maybe we can do something
on the driver side (like forcing a resolution change even if not necessary)
to work around this. Laurent ?
Note re-adding the mailing list and Laurent to the CC, they somehow got
dropped.

Zoomed in ? Really ? As far as I know the QuickCam Pro for Notebooks has no
optical or digital zoom. Could you please send me lsusb's output for your
device ?

The driver already sends a video format and resolution set request to the
device when starting the video stream.

Yes. I can use digital zoom under M$Win with Logitech software. lsusb
