USB webcam weirdness

[Net Llama!]

I've got a Philips 690 USB webcam, which was working flawlessly until I
started using it on an old laptop running FC3.

Now it runs ok for several hours (where several is anywhere from 12-15)
and then it suddenly stops capturing images.  The weird thing is that its
not generating any errors, its just that the image which is getting
captured is blank.  Here's what i'm referring to:

What you should be seeing is the view from outside my living room window.

I've checked messages log and there are no errors.  Everything that is
logged is as if all is normal.  The only way i've found to fix this right
now is to manually unplug and replug the camera into the USB port.  Then
it works fine again for several hours, and the cycle begins again.

Since there are no errors anywhere, i'm at a bit of a loss as to what is
going on.  Anyone have any suggestions on how to troubleshoot this
further?
