Everytime I plug my PW3 into my computer, I get an eye-tracker software popup saying "Tobii Eye Tracker detected." It would be nice to get rid of that. Unfortunately, that driver assumes any RNDIS device is its eye-tracker, apparently, and it makes no attempt to look deeper...
At least I can still SSH into my kindle, which makes me wonder what I will find if I SSH into my real eye-tracker when it is plugged in -- and can I root it?
