dear experts:
quick hardware question: is power additive? that is, assume I have a 1A USB 5V adapter installed.
if I now add a standard powered USB 2.0 connection (0.5A) to my (1A) USB 5V cable, does the BBB now have 1.5A?
my hard drive shipped with a y-cable, that presumably helps it to draw 500mA*2. if I connect it to the BBB, can it draw 2A then? (or, if I only connect it, can the BBB draw 0.5A or 1A).
