holgt, I hope you can help me. I've bought a Lapdock to use with my Parallella, and I'm very interested in the solution you came up with for powering the Parallella through a USB port of the Lapdock. I found a similar cable to the one you're using on Sparkfun (I checked it's the right polarity)...https://www.sparkfun.com/products/8639
However, as Sparkfun points out, this would only give me 500mA, and the Parallella needs around 2000mA... http://www.parallella.org/quick-start/
How are you getting the extra juice for your Parallella? Please help me, I don't understand!!
If anyone else knows a bit about power over USB, please share, maybe there's something I've missed.
