Description of problem: When I will use my webcam with emesene or cheese, the kernel log says "uvcvideo: Failed to resubmit video URB (-27)" like in the Bug 600998. But webcam works with ekiga. Version-Release number of selected component (if applicable): Fedora 13 How reproducible: Use a webcam's user software Steps to Reproduce: 1.Load a kernel after the 2.6.32 series 2.Use a webcam's user software 3. Actual results: A black screen Expected results: Webcam's frame Additional info: I tried some Fedora's kernel (from 2.6.32 to 2.6.35). Only the 2.6.32 series works with a lot of difficulties. My webcam is (Bus 002 Device 002: ID 064e:a116 Suyin Corp). My laptop is an Asus K50AD series
Hi, Can you try the kernel-2.6.34.3-37.fc13 update please, see bug 600998 comment 11 for installation instructions. Thanks, Hans
Hi, I updated the kernel to kernel-2.6.34.3-37.fc13 but it doesn't work anymore with all software. The kernel log message is still "uvcvideo: Failed to resubmit video URB (-27)".
Ok, thanks for trying. I'll get the uvcvideo driver author to talk to you further about this. He will likely ask you to create some debug logs.
Hi. Yes, I can create debug logs but which logs you want to have?
-27 is -EFBIG, and means "Host controller driver can't schedule that many ISO frames." It's a low-level issue that might indicate a bug in the EHCI driver. I don't think there's much I can do in the uvcvideo driver. Could you get in touch with the USB core and EHCI developers (through the linux-usb mailing list) ?
Closing this as cantfix per comment #5.
