Description David Oboeuf 2010-08-11 14:32:18 EDT
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)".
Comment 3 Hans de Goede 2010-08-12 09:35:05 EDT
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.
Comment 4 David Oboeuf 2010-08-13 05:19:58 EDT
Hi. 

Yes, I can create debug logs but which logs you want to have?
Comment 5 Laurent Pinchart 2011-02-15 13:51:54 EST
-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.
