As I read it, DA52 has tried using a USB camera (post #156) and is suffering a lot of lag.

Historically speaking USB comms had to go through a bit of a bottleneck on the Pi since all USB traffic went through one narrow channel, or that was my understanding - That may have improved on the later models.

Imagine trying to initiate an action on the online connected MK14 and not seeing it respond for several seconds, it would be like trying to speak while listening to your own delayed voice.

The 'proper' cameras for the Pi seem to have their own exclusive highway over which to communicate with the Pi.
