and if i just run "ls video"
i get these results

[root@h24-71-50-105 dev]# ls video
em8300 em8300_ma em8300_mv em8300_sp

The em8300 is the device name for a hollywood+ or creative dxr3 dvd decoder, nothing to do with the webcam.
Your video devices are there and the permissions look ok, what type of motherboard do you have?
I'm thinking that maybe the wrong usb controller module may be loaded.

i have an AMD-athlon xp1800

Like Aussie said it might be the wrong usb module. It varies greatly which usb module works. On my computer both the uhci and the usb-uhci module work. I do however need to also load the ehci-hcd module for USB 2.0 support. If I don't then the webcam light never even turns on and it never gets registered with the USB driver.

But like I said before you really need to be reading through the output of dmesg (also found in /var/log/messages usually). It tells you whether the device has been registered and if the webcam driver detected the camera properly. It should give you a few clues where to go from there. So run the command dmesg and post the part relating to the usb and the webcam.

You didn't add the part about the pwc modules being loaded. But anyways here is some more information.

The usb driver detects two devices. The first it claims to be unknown and the second is your mouse. It gives the following information about the unknown device (vend/prod 0x46d/0x8b3)
The first being the vendor number for Logitech and the second being the product number for the QuickCam Zoom. I checked in my own kernel sources (2.4.20) and it is not supported yet. So I went to the site to check on the latest version and apparently the QuickCam Zoom is only supported from driver version 8.9 and upwards and will only be included in the 2.4.21 kernel which isn't out yet. So you will have to download the latest version and compile it yourself. It would probably be easier if you compile for a kernel from www.kernel.org instead of adding it to the redhat kernel you already have.
