2.6.33.5-112.fc13.x86_64 Apple MacbookAir 1,1 Bus 002 Device 003: ID 05ac:8505 Apple, Inc. Built-in iSight When using Empathy or Cheese, I get loads of: uvcvideo: Failed to resubmit video URB (-27). uvcvideo: Failed to resubmit video URB (-27). uvcvideo: Failed to resubmit video URB (-27). messages in the kernel log. That webcam used to work great under F12 and earlier F13 kernels.

Bastien, Can you attach the full output of dmesg please ? In the mean time I'll ask the upstream uvcvideo driver author to take a look at this bug. Regards, Hans

The dmesg output is really that useless. uvcvideo driver being loaded, errors as above repeated a number of times. Cheese and Empathy manage to get the first frame after reloading the webcam module, and that's it.
Hi Bastien, Ouch. -27 is -EFBIG, and according to Documentation/usb/error-codes.txt in the Linux kernel source tree it means that the "Host controller driver can't schedule that many ISO frames". I've had a look at the EHCI driver, and -EFBIG is only returned by the iso_stream_schedule function in drivers/usb/host/ehci-sched.c. That code has been modified between 2.6.32 and 2.6.33-rc1 (commit dccd574cccad950d9ed9bc192eae4089c6044d9d). Would by any chance the early F13 kernels be <= 2.6.32 ?
Very early F13 kernels were 2.6.32: http://koji.fedoraproject.org/koji/buildinfo?buildID=150428 http://koji.fedoraproject.org/koji/buildinfo?buildID=149757 http://koji.fedoraproject.org/koji/buildinfo?buildID=148518 but switched to 2.6.33 in early January 2010.
Should be fixed in 2.6.34.1-17
You can download a hopefully fixed kernel for F-13 here: http://koji.fedoraproject.org/koji/buildinfo?buildID=184570 Please give it a spin and let me know if this fixes this.
