I would like some precision about the issue with upside down image and the messed up image.

Do the upside down image goes right up after a short time?
Several mounths ago the images started AND STAID upside down in poorly lit conditions. This was solved with the driver waiting for 3 images to be received and only after that setting parameters (orientation, brightness and so on).
If the image is upside down at the start and then becomes right up, it is not the same issue. Cheese is really slow and maybe it does not refresh its frame quickly enough. i made a test with my webcam (05e3:f191), it needed 7s to get an image in video mode although my driver flavour has far less data to send and no delay between each USB commands.

About the messed up images: do they are still present with the 2.6.27c driver when Cheese is started from KRunner?

-----------------------------------------------------------------

Some news about the driver. I made a version with two new additions:
- autodetection of the flavour to use
- two duty modes: relying on libv4l (no more image decoding by the driver) and normal one (the driver decodes and resize the images). The first mode is better for the kernel as this should not be done by the driver. However almost nothing is working in 64bits. I froze my system two times when the driver was not relying on the libv4l although I have not any report about system freeze by other testers (except Ekiga maybe). No such issue with libv4l.
