Recently I've installed Mint 7 (main, 32bits) on the computer I've built for my mother. Chatting with family on Skype is one of the primary things it is going to be used for, so I tried if the Logitech webcam I have would work there (it should, worked out of the box on Lenny @ my own workstation). It turned out, it didn't, even though I installed all the (possibly) required packages before connecting the thing (qc-usb-source, "-"-utils, xserver-xorg-video-v4l, v4l-conf, setpwc).
On my mom's PC the device doesn't even show up in /dev/, on my own (also Mint 7) it does but luvcview and xawtv get nothing but a grey image out of it. However, in both cases the device gets recognized by lsusb:
Now Helena's out, I decided to give the give it a shot. Started up the liveCD (main, 32 bits as well, on my own PC), installed all the packages again, played around with settings... still the same result (well, the grey color does respond to what I do with brightness/contrast/sharpness, just no image appears). The output of setpwc -p might be useful:Bus 001 Device 004: ID 046d:09a1 Logitech, Inc. QuickCam Communicate MP/S5500

EDIT: the main difference between my mom's PC's hardware and my own is the main board, I bought her an Asus P5QPL-VM EPU and my own is P5E-VM SE. Her onboard graphics are good enough so I decided she wouldn't need a video card. I have an Sparkle GeForce 9600GT. But even when I had Radeon HD 4670, the webcam worked fine (in Debian).mint@mint /dev $ lspci

That's about it, I would appreciate any help on getting the thing to work. I might have overlooked something, so if you need more information, feel free to ask.
Tnx in advance.
