[Bug 309540] New: uvc camera not working any more
https://bugzilla.novell.com/show_bug.cgi?id=309540 Summary: uvc camera not working any more Product: openSUSE 10.3 Version: Beta 3 Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: msvec@novell.com QAContact: qa@suse.de Found By: --- Creative Live! Cam Optia does not work any more (using luvcview for instance) on 10.3 beta3, on 10.2 it works well. As the software is the same, I suppose the problem is in the kernel.

With exactly the same hardware it works on 10.2 and does not on 10.3-beta3. Regarding the bandwidth, I have also USB mouse and keyboard (and a USB hub), the keyboard seems to cause problems, if I disconnect it, the camera works. I don't think the keyboard should generate too much bandwidth, though :-) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

And, the keyboard's data takes priority as it is "control" data, so it always needs to succeed, while the camera data can be thrown away... I think you just need a new USB controller for just this camera, or for your keyboard/mouse combo, you are running out of room on this one host. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Yes, it looks like the patch Greg and Oliver are referring to won't be making it into 2.6.25. I will let you know when I have a Kernel you can test. (In reply to comment #19 from Pavel Machek)
