According to the install notes you should already have a kernel module for this cam, see what happens if you do "modprobe pwc".

When modprobe does nothing then that means that the module loaded correctly. Have you tried using the cam yet?

Cool, now cd to /dev, su to root and do the following
Code:
./MAKEDEV video

followed by

chmod 666 video*
Then try xawtv again.

Do 'ls -al /dev/video*' and post the output, and post the entire output of 'lsmod' please.

Well there are two modules. One of them (pwc) is open source and is included in the kernel. The second module (pwcx) is closed source and contains decompression routines. The second module isn't necessary if you want to run at a really low frame rate and use a very small image size.
Either way if you have the modules for your usb and pwc loaded then you should see someting like this in your dmesg output when you attach the webcam:

hub.c: new USB device 00:10.0-2, assigned address 2
pwc Philips PCVC740K (ToUCam Pro) USB webcam detected.
pwc Registered as /dev/video1.

This will also tell you which device it connected to. Usually this would be /dev/video0 if you only have one video device connected.

I don't know what kernel version you are running with redhat. But you might want to try to get the latest version of the driver from the site that Aussie gave you.

Either way you might want to post the output of dmesg, at least the webcam part.
