kernel .config for gentoo-sources-2.6.30-r1
Anything in dmesg like this? uvcvideo: Found UVC 1.00 device Namuga 1.3M Webcam (0ac8:c326) Yes: [ 5.791981] uvcvideo: Found UVC 1.00 device Namuga 1.3M Webcam (0ac8:c326) [ 5.794325] input: Namuga 1.3M Webcam as /devices/pci0000:00/0000:00:1d.7/usb1/1-8/1-8:1.0/input/input7 [ 5.794683] usbcore: registered new interface driver uvcvideo [ 5.794696] USB Video Class driver (v0.1.0) I see a good number of uvcvideo commits in the development kernel. Can you test the latest git sources, which is git-sources-2.6.31_rc2-r9? Same as before I'm afraid :( Let me know if you want a dmesg but I think the relevant output is all the same as for 2.6.30*. All gone a bit quiet ... is there anything I can be doing to help debug this? If so, please do say so. I realise Skype being closed-source isn't the best test-bed, but other users are reporting the same issues with other webcam apps as of 2.6.30* and I am quite willing to run tests with other apps if it will help to dig into this problem. i think that the bug reported here[1] is the same as this one try the patch for uvc_driver.c from the v4l-dvb tree[2] it should work for both 2.6.30 and 2.6.31-rc's [1]http://bugzilla.kernel.org/show_bug.cgi?id=13682 [2]http://linuxtv.org/hg/v4l-dvb/rev/da81aafb9c5d Created attachment 200365 [details, diff]
uvc_vimicro_fix.patch
the patch from the v4l-dvb tree
The patch hasn't helped. I also tried running the v4l2grab util mentioned in the kernel bugreport, but it only produced one image and exited with: Error 20: Illegal argument (I think that's what it said, I had a panic after running it a second time.) The one image output was 95% covered in snow, with a narrow strip of the true picture along the top. Can you please test with gentoo-sources-2.6.31-r1 and let us know the outcome Working in skype with 2.6.31-r1, thanks. |
