Intel webcam CS330 not working properly

[Andy Price]

Hi

I'm trying to get my old Intel CS330 webcam working under VL6 Standard. When I open the wxcam application I don't get a proper picture. I've tried every combination of Frame format and Driver - sometimes it's blank, sometimes green lines etc.

Below are the outputs from lsusb, lspci and lsmod (which were asked for in another webcam-related query).

I've read some place that gspca is supposed to support this webcam so any ideas how I can get it working?

Thanks
Andy

Apparently your webcam is supported by the gspca driver, but not by the one included in VL.
Try to build another one from source, we need to patch it for recent kernels. Login as root and run:

Code:

wget http://mxhaard.free.fr/spca50x/Download/gspcav1-20071224.tar.gz
tar xvf gspcav1-20071224.tar.gz && cd gspcav1-20071224
wget http://www.slackware.com/~alien/slackbuilds/gspcav1/build/gspca_kernel_2.6.27.diff
patch -p1 <gspca_kernel_2.6.27.diff
make && make install

That will install the driver, now we need to remove the old ones before loading the new one:

Code:

modprobe -r gspca_spca501
modprobe -r gspca_main

Now insert the new compiled module:

Code:

modprobe gspca

Now you should be able to test your cam. If it work we will need to blacklist the offending modules so they are not inserted in the kernel at boot time anymore:

Code:

echo "blacklist gspca_spca501" >> /etc/modprobe.d/blacklist

Let us know how it goes.

EDIT: I corrected a path, is modprobe.d instead modules.d

Thanks for the quick reply, worked a treat. Can't beat the help given on this forum!

Sligthly off topic, but should the settings you make to the image balance (contrast etc) be retained when you close wxcam? For me they are lost and I have to set them each time. I tried adding lines such as Contrast: 50 into the ~/ .wxcam file, but no joy.
Thanks
