You're right, although anecdotally speaking... every time I've turned on my Samsung TV for the past 10 months, it lists the USB port as the most recently used source on my TV. It never did this before.
That is extra strange since I've never used the USB port on my TV, and the TV has been installed rather high on a wall behind my desk since the day it arrived so it would be nearly impossible for my wife or small children to get at the USB port, let alone plug in a valid source... unless it was being used as an exploit by some software in the TV.
I'm not suggesting that is what is happening, however, it is suspicious as hell.
