Need detailed example of how to use my SB5101 in compatibility mode

I have a Motorola SB5101 USB Cable Modem and I have gone through many of the threads and none of them seem to be helpful. I read about how to use it on windows 7 using compatibility mode due to the fact that its made to be used on xp and previous os. Could someone provide me with a detailed example of how to use it using compatibility mode or if there is another solution please tell me.
