ZC0301 Webcam Problem

Tue Nov 04, 2008 11:16 pm
Hi, First no idea if this is the right forum or if I'm being off-topic.
The situation is as follows. I have a Genius Look 312P Webcam.

Now from lsusb I know that is is a zc0301 with vendor 0ac8.
Code: Select all
Bus 003 Device 002: ID 0ac8:301b Z-Star Microelectronics Corp. ZC0301 WebCam

And in the linux kernel config I have chosen to compile as module two drivers

One is 'USB GSPCA driver' and the is 'USB ZC0301[P] Image Processor and Control Chip support'

With the USB ZC0301[P] one it dmesg says
Code: Select all
 zc0301: V4L2 driver for ZC0301[P] Image Processor and Control Chip v1:1.10
usbcore: registered new interface driver zc0301

but no video device is created.

with USB GSPCA I get a /dev/video1 but it doesn't work (neither in kopete nor skype)
dmesg for that module says:
Code: Select all
 zc3xx: probe 2wr ov vga 0x0000
 zc3xx: probe sensor -> 11
 zc3xx: Find Sensor HV7131R(c)
 usbcore: registered new interface driver zc3xx
 zc3xx: registered


Any Ideas how to make my webcam work? Thanks in Advance

In Linux 2.6.27, they finally added the gspca drivers into the kernel itself, however, they also took some things out.

To have things working, you will need to use libv4l, which you may need to install.

So to have the new libraries loaded into Kopete (or Skype) you will have to use the LD_PRELOAD variable (assuming you have v4lcompat.so in the place as me), and start it like this:

Code: Select all
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so kopete


...and your video should work!

Thanks! After I emerged the library now I can see myself in the Configure Dialog!
Now I've got to see how do I forward a port if I'm using dhcp (I had static IP previously so I could make reference to my machine by IP, now I don't know)
