Hello there!

my router yakumo wireless storage runs with freifunk-firmware-1.4.5. its based on openwrt whiterussian rc5. i have installed the following modules/packages to run my philips webcam toucam II PCVC820.
ipkg install  kmod-usb-ohci  kmod-videodev  libpthread  libjpeg  motion; and the drivermodules for the camera: ov511.o  ov518_decomp.o

dmesg says:
<pre>

usb.c: registered new driver ov511
ov511.c: USB OV518 video device found

I have a similar problem with Hercules Webcam Deluxe (ov51x) on ASUS WL-500gd with rc6. The output resembles your one, but it is cleanly green with noise of different green shades in the upper part. I'll post the image later.

ok.

the problem is the weakly router. I tested with asus wl500gp and it works fine.
I think the yakumo-router has to few power (125 mhz) and an old usb-controler (usb-ohci).

Well, here's the image I promised before.

But a cause of it is probably very different.

The discussion might have continued from here.
