Well I must be getting close.
I put the line in, typed it just like this

none /proc/bus/usb usbdevfs defaults 0 0

I can see my usb items including the camera in system, info center.

When I go into control center I can also see the camera icon, but when I click on the test button I get,

error message

Unable to initialize camera. Check your port settings and camera connectivity and try again.

When I type camera:/ in the location bar on Konqueror it see's the camera as a file, but when I click on the camera file I get the error message,

Could not read file /

Did I maybe type in the line wrong?

Thanks

BTW: I rebooted after saving the new line, do I have to reboot after adding the line?
