The serial bus controllers are part of windows. Your system should already have them installed.

Go to start-->control panel-->system-->hardware tab-->device manager-->is USB serial bus controllers listed there?

[#0005ff]Try restarting the computer and go into Safe Mode by tapping Function 8 as XP starts to load. Log in as Administrator - pray to whoever you will that there isn't a password for that account - and try again. The System Administrator has more rights than a User with a Computer Administrator account.[/#000ff]
