I would like to know if it is possible to connect usb cameras directly with RPi B+? While working with RPi Model B, I had to use a powered USB hub to interface with my i-ball camera, but with 4 ports in B+, is it possible to interface the camera directly, without a powered hub? The camera which I'm planning to use needs an input of 5V/1A. The RPi can deliver upto a max of 1.2A for the 4 usb ports.
Also, I am thinking of a project where I would require 2 USB cameras, so is it possible to use 2 usb cameras with the same RPi B+? If I go with the 5V/1A camera, obviously the current rating will go to 2A and the Pi won't be able to deliver it from the usb ports, right?
