The Logitech Quickcam Pro 3000 uses the Phillips webcam driver (pwc) which should already be present in lucid
BUT
I'm finding conflicting reports on the Logitech Quickcam Pro 3000
Some say the camera doesn't work if plugged in when the computer is switched on, and must be plugged in after the PC has finished booting.
Others say the opposite... It MUST be plugged in at boot time.

I'm also finding reports that it will NOT be detected properly if plugged into a USB hub, but works if plugged directly into a USB port.




You could try this... Unplug the camera, then in a terminal:
Code: [Select]
sudo modprobe -r pwc
then plug the camera back in... give it a few seconds, then to check the driver module has loaded... in a terminal:
Code: [Select]
lsmod | grep pwc
and see if anything is returned... if it does return something, try your camera

if nothing is returned, in a terminal:
Code: [Select]
sudo modprobe pwc
now try the camera.




If still nothing post the results of:
Code: [Select]
lsusb | grep Logitech
and:
Code: [Select]
lsmod | grep pwc




you might also want to install setpwc (CLI tool for changing the settings of cameras based on the Phillips webcam) either through your package manager (Synaptic) or from a terminal:
Code: [Select]
sudo apt-get update && sudo apt-get setpwc

and change the cameras settings back to default with:
Code: [Select]
setpwc -x
then set the frame rate  to 30 frames a second with:
Code: [Select]
setpwc -f 30
and white-balance to outdoors if you are in a light room with:
Code: [Select]
setpwc -w outdoor

if you want to see all the settings that can be made with setpwc:
Code: [Select]
man setpwc

The E 3500 uses the uvcvideo drivers which you already have installed.

It is also a v4l2 device... apparently Camorama doesn't support v4l2 devices

Try using it in either luvcview, cheese or ekiga instead of camorama... all available in synaptic.

Ekiga definitely supports v4l2 devices, but you may have to change the video device from v4l to v4l2 somewhere in its settings.
