Help: MCBOOT Installation

I'm looking to an alternative to installing MCBOOT. I have Code Breaker , Game Shark, and a working USB Drive. I tried following the CB tutorial, but the CB version i have is 10 and for some reason they don't seem to be working with USB ports on a Slim PS2 . I have looked around forums for some time and there is no solution for making the USB work with the CB version 10. I have a unmodded slime PS2 and am wondering if it is possible to install it with Game Shark. I have tried getting the files on my memory card with the Game Shark and try using the Codebreaker to install it, but no luck.

@The2nd:
It is a known bug with all CodeBreaker versions that they do not work with USB devices on the slim PStwo models SCPH-7500x and all later ones. Not only does CB USB access fail on those models, but the CB program will not even boot correctly if any USB device is connected to the console.
