OV511+ Webcam

[hydro]

I would like to get snapshots from an old webcam attached at the DockStar
$this->bbcode_second_pass_code('', '
$ lsusb
Bus 001 Device 010: ID 05a9:a511 OmniVision Technologies, Inc. OV511+ Webcam
')
$this->bbcode_second_pass_code('', '
$ dmesg

input: ov519 as /devices/platform/orion-ehci.0/usb1/1-1/1-1.4/input/input2
')
The cam is supported by the gspca driver included in kernel 3.0.3-1 ARCH.
$this->bbcode_second_pass_code('', '
$ lsmod

i2c_core 15432 1 videodev
')
To get a snapshot I run fswebcam
$this->bbcode_second_pass_code('', '

But the image is completely useless, see attachment. Same result with my custom kernel 3.0.1.
Same result also when I use v4lctl (included in xawtv)
$this->bbcode_second_pass_code('', '

When I use the camera on my computer running Arch Linux i686 (kernel 3.0.4-1 ARCH) I get useful images with (almost) identical output of above commands (differences only concerning USB bus). Why not on the DockStar?
I have used ov51x-jpeg from AUR from time to time instead of gspca_ov519, but it cannot be compiled since kernel 2.6.39.

Since this problem still persists with current kernel 3.1.4, I finally bought a new webcam that works fine with the uvcvideo module.

I knew it. Appears I have 3 webcams all become obsolete.
