Hi JW
My question is How can I find drivers for this webcam
As I noted a mepis user member has a camera that may be the same make
Can I attach a jpeg file to this text message?

The linux USB devices list has this camera (exact same vendor/device ID) as 'not working'. See:

http://www.qbik.ch/usb/devices/searc...pattern=z-star

But there is a comment there that it might be using the OV7648 sensor. Googling for 'OV7648' with 'linux' gets a number of hits, such as this one:

http://www.linux-projects.org/module...hp?storyid=119

which advertises a working driver. Googling the driver name takes us back the USB devices list which says the driver is in the kernel....

http://www.qbik.ch/usb/devices/showdr.php?id=89

The kernel module is called 'sn9c102'. You could try 'modprobe sn9c102' and see if the camera is detected. If not, well, maybe the original comment was wrong

Plenty of other Google trails to follow. Might be worth trying the latest kernel also if possible. Support for this sensor might only have been added recently.

Isn't that your camera at the top of the list on my first link?

Anyway, have you tried the sn9c102 driver? What kernel version do you have (check output of 'uname -r' if you are not sure)?

Never seen a JPEG posted since finding this site. I think you would need to have the picture online and provide a link. I doubt it would help you much. The vendor/product ID is more reliable than a picture.

Yes you are right camera is on the list on your first link
Have used modprobe sn9c102 with the USB camera connected. Nothing shown.

Have downloded the gspcav1 20070508 tar.gz
Untared and used Synaptic to installLinux-Headers
To Make and install
Now I need to find the command that will run an executable command
Any Idea
Maurice

You got me there. I am not sure what you mean. It sounds like you are asking how to run a command from the shell, but since you are using 'modprobe' and 'lsusb' I assume you know how to do that.

What exactly happened when you tried 'modprobe sn9c102'? If no message that means the module loaded OK. Then try unplugging/replugging the camera and running 'dmesg' command. Check last few lines of output to see if cam is claimed by any driver.

Otherwise the other driver you have d/l'ed might be worth a try.

Again - making sure you have a recent kernel might help.

Well the driver loaded OK. Did you unplug/replug the camera before running dmesg? Usually even if there is no driver available there should be a couple of lines acknowledging that a USB device has been plugged in.
