Omission of second webcam from My Computer

Archived from groups: microsoft.public.windowsxp.video (More info?)

I hope this is the right place to be asking this. If not, my apologies.

I'm using XP Professional with all updates installed.

I have 2 usb webcams, each plugged into its own USB 1.1 port on my computer.
(I'm doing that to decide which is best. Also, neither of them supports USB
2.)

When I open software which came with one of them (VideoLive Mail), I can
switch between the two cameras within the program and get video from each of
them in turn in that way.

However, when I open My Computer, only the first in time of the two I
installed is represented by an icon. I can just doubleclick on that icon and
get video that way as well (although I'm not sure what causes that to
happen).

How do I get an icon for the second webcam to appear in My Computer?
