Handy Hint - to find out if a network cable is a crossover cable, hold the two connectors with the metal contacts facing you and the cable pointing down. Reading from the left if wires 1,2,3 and 6 are the same colours in both you have a normal straight-through cable. If 1+2 go to 3+6 and vice versa you have a crossover cable.

A crossover cable can be used to link two PCs or Xboxes without a hub. Any crossover cable will do, it does not have to be the expensive Microsoft recommended one. You can also link two Xboxes with two normal cables and a hub.
