Arch Linux

Description:
I'm using the playstation eye camera on archlinux for a project. On kernel 2.6.35-8-3, everything works beautifully. I am mostly talking here about image capture. When I upgraded to the new kernel (2.5.36-1-3), the camera capture stopped working. When I downgraded again, the camera works as intended.

The only changes in my sistem were the kernel, nvidia driver and ndiswrapper, since those two depend on the kernel version.

What works:
/dev/video1 node gets created
ioctl works on the node,
v4l2-ctl was able to list the video modes and everything. Setting the video mode also worked.

What does not work:
cat /dev/video1 fails with the error: input/output error (my guess is fopen() fails).

I will be happy to provide any additional info and will do any steps required to debug this, including reinstalling / recompiling the kernel and applying patches if necessary.

Other (possibly) useful debug stuff:
atom@kamichan /var/cache/pacman/pkg $ v4l2-compliance -d /dev/video1
