I thought I had something in the office about this, but can't find it (!) However, it's probably easier to buy the "crossover" as a patch cable from your local dealer; most stockists hold both the "straight" and "crossover" patch cables to connect from wall plug to computer.
Just don't forget to replace the crossover with a straight when you introduce the hub into the system!
Good luck.
