Not quite. The cameras have to be connected to different USB
busses/controllers. If you do that, then both should work in the same time,
without any performance loss.

Use "usbview" to see that the cameras really are on different controllers.
If your computer has just two USB ports chances are that it has just
one controller and you cant use _simultaneously_ two cameras.

>i load the quickcam module i still only see /dev/video1.

Are you using 2.4.x kernel with videoprocfs? If so, go to
	cd /proc/video/quickcam
	ls
it should list something like
	video1 video2
which would mean that video1 and video2 are the two cameras found.
If it displays only one devices, it generally means that only one
supported camera is found.

If you are _not_ using devfs, the device files in /dev are not created
automatically and maybe you just don't have enough of them already.
You can create more with mknod (see FAQ at
http://www.ee.oulu.fi/~tuukkat/quickcam/FAQ)
	mknod /dev/video0 c 81 0
	mknod /dev/video1 c 81 1
	mknod /dev/video2 c 81 2
	mknod /dev/video3 c 81 3
	chmod a+r /dev/video?
	ln -s /dev/video0 /dev/video
