Hi ! you have a lot of chance because I do not look at this page often. Please go to http://ubuntuforums.org/showthread.php?t=869263 next times.
After some google search, this error occured also with kernel 2.6.26something. Try what is in this post to solve the trouble : http://www.gossamer-threads.com/lists/linux/kernel/951452 and reports the result.

I tried compiling the GIT version, as the released version on sf.net, but i get (with 2.6.27-rc4) the following error:

~/compile/nvgl$ ./install

What do you make of that?

OK thanks. There is no data in the logs I didn’t use and that was important for the driver.

Sorry, had no time before to make this log:

http://michael-gerhaeuser.de/gl860/brightness_min_max.log.c

no brightness changes in the captured images, so only the log.c file.

@ Amighurt or Sur3

Hello, I need to be sure about the settings of parameter which are not asked to the webcam by the driver. So could you make a log while changing the brightness from the minimum to the maximum after the brightness of the picture is steady (not during the start of the webcam when the lumonisity chnages). If in the images created by relog there is no change in brightness, no problem, if there is a
change, i need the raw log (not processed with relog).
Thanks

Don’t take these images into account.
Relog try to find the width and height of an image with the approximate number of bytes received and with Height=4/3*Width. Then it keeps as width the nearest of 320, 640, 800, 1024, 1280 or 1600 and infers a new height. When there is no prefered width near enough, it keeps the former width.
You have weird sizes because while making logs, there is too many data to log and USBSniff misses data, so you have smaller pictures than expected because image data were lost or bigger pictures because “end of image marker” were lost and the number of bytes received is that of 2 images or less depending on the data loss.

If you have clean images in 1280×960, that is the webcam send 1280×960 images.

Of course, but you won’t see much. Most of the image is white and black, just the upper part looks like there is something captured:

(converted to png, original bmp has about 5MB)

And with sizes >= 640×480 there are only such pictures, nothing to see, mostly black, weird sizes (not only 1600×1080 but also 1600×1000, 1600×1002)

Could you show me a picture in 1600×1080.

almighurt — Mon, 16 Jun 2008 21:10:24 +0000

p.s.: yes, it’s really 1600×1080 and NOT 1600×1280 it’s not a typo.
