Don't known but probably USB (power) not working in Raspberry Pi B+ . Find somewhere on forum could be PSU problem . Try 5 different (1 strong from Ipad) and still the same. Works fine on Raspbmc.
HDMI output is too bright and the mystery is solved here with the registered version and some other kinds. The registered version is by mystical 86 that is just installed a new beta version with redbubble artist that has got a problem with the too bright video in the outputs.
