Please log in for more thread options The hardware device that you see in device manager is most likely a USB
controller or "root hub", not an RS-232 port.
Where did you get the XP that you installed? The fact that you did a
clean install doesn't mean that you have [all of] the proper drivers for
the laptop ... in fact, you normally wouldn't. You would normally have
to go to the Toshiba web site and get all of the necessary drivers, and
install them (and there could be a dozen or more). Even an XP CD
obtained from Toshiba might not have all of the necessary drivers on it
(however, I would expect that a model specific image-based
reinstallation CD, as opposed to a generic Windows XP CD, would have the
drivers).
Also, go into the BIOS setup and see if any of the laptop's devices are
disabled. That could well be the case.
