It sounds like you did a number of things that are not in the guide you linked to.
You don't have to enable USBnet. You do need to install KSM8 following the directions in the first post of that thread.
What kind of PC are you talking about? Linux, Mac, or Windows #?
Once KSM8 is installed properly, all you need to do to "install" the other readers and software is to place their folders where KSM8 expects to find them.
Luck;
Ken
