  USB Output Power

  The resetable fuses protecting the USB outputs have been removed. This
  feature was implemented on some later revision 1.0 PCBs by replacing
  the fuses with links; revision 2.0 permanently implements this
  modification. It is now possible to reliably power the RPI from a USB
  hub that back feeds power, but it is important that the chosen hub
  cannot supply more than 2.5A under fault conditions.
