Check the documentation of your computer (mainboard). It
should note where the ports are located. In systems that
have _both_ USB 1.0 and 2.0, there sometimes is even a
red sticker to "alert" you which ports are only USB 1.0.
The manual of the board depicts which USB ports are those.
Typical places would be rear side, internal connectors,
and front ports (connected to those internal ones).

If you do not have any documentation, take a USB 2.0 device
(where you are _sure_ it's USB 2.0) and try it on all the
ports. Check the dmesg output informing you about how the
device has been initialized (e. g. transfer speed mentioned).
You can also use usbconfig to obtain this information.
