Many computers will have a couple different locations for USB ports and some may be newer USB 3.0 or 2.0 which are faster than the older USB 1.00 specification so if your MOBO has different connectors try using a different one to see if it is connected to one off the newer higher speed connections - Which ones are faster or how many of the higher speed connections are on the system varies so without knowing the specifics about your system there is no way to tell you which is which on your system.
