I have not set up any of my logitech G-keys. But I am sure if you read the suspension info they "IMPLY" that some people may have been using some sort of automated key stroke. Again if memory serves me right there is a way to set up key bindings so you can mine or craft the same last thing without mouse clicking. Which may require some attention but would allow for you to semi HQ with out paying any attention. None of the people suspended ever admitted to using any outside program.

But generally like other people have suggested just uninstall drivers put fresh ones in and usually poof they work again.
