Do you mean the enable/disable buttons?

If so, it's because I haven't yet found a way to find out if the drivers are already loaded or not, so both the enable and disable buttons are always active.

It doesn't mean they don't work it just means there is no confirmation to say that they have loaded. Trust me, if you installed the drivers correctly then it will work fine. Just remember to disable it when you are done so it doesn't eat your battery life.
