Razer Hydra with Javascript

I'm trying to get the Razer Hydra to work in my Unity projects. I got the tracking to work, but have problems with the input. I'm using javascript, and even though I understand something from the .cs scripts from Sixense plugin and Teddy's integrations, I can't get it to work in javascipt.
With quick look I couldn't find any tutorial or guide for javascipt input of Hydras. Is it really that hard or could someone explain briefly how it's done?
