Bad answer! I want to know the vendor and product IDs and also which
Linux driver handles your webcam. Please do:
	lsusb
and
	dmesg | tail -20
after connecting the webcam.

the old cam has this:

Bus 002 Device 002: ID 046d:0840 Logitech, Inc. QuickCam Express


[ 2040.384046] usb 2-5: new full speed USB device using ohci_hcd and address 4

i bought another quickcam (communicate model) and tried it out and got this:

(the video portion of it didn't register)

I have one of these, too.
This one mostly works with the one-liner posted at [1].
Open problems include:
- console spammed with lines like
  "libv4lconvert: Error decompressing JPEG: unknown huffman code: 0000ffec"
  (and the last 8 picture lines are green)
- led control doesn't work

The data posted at [2] (USB dump using Windows drivers) can also be of
some interest.
