Look for an "Enhanced" USB host controller. Also, if you plug a USB 2 device
into a USB 1 port, there will be a warning that it would run faster in a USB
2 port. Device manager won't specify which ports on the computer are USB 2.

In the USB category if you see a Controller with the "Enhanced" keyword
in the description. Internally USB is routed by it's technology. So no
matter
which socket you use if it's a USB2.0 device it routes to that controller &
it's associated Hub. USB 1(.1) devices have dedicated controller-hubs that
are socket dependant. This is why you see more Non-Enhanced Controllers
and hubs than Enhanced.

As far as I know there's no way of determining from within XP if a given USB
port is USB 2.0 capable or not. If the USB enhanced section is visible in
device manager and functioning properly, it just means at least one USB
controller is USB 2.0 capable and functioning.

One can tell, by examining the properites of a given USB port in device
manager, what USB device is attached to it if the USB device is recognized.

Motherboard manuafacturers usually divulge which ports are not USB 2.0
capable if so provided, if USB 2.0 capability is advertised as an asset on
that motherboard. Not sure about PC manufacturers.

If you are lucky, the high speed ports will be described as 'enhanced' in
device manager, but the absence of that description doesn't prove that they
are not. If not then:

Open each of your root hubs in turn and select the power tab. This shows
how many physical ports each hub serves (usually 2 each for the low speed
root hubs). The total number of ports should be double the number of
physical ports, though it should be remebered that not all the physical
ports may make it to connectors on the outside of the case (particularly
with laptops). A give away is that the high speed root ports usually serve
more than 2 physical ports.
