So, what would be the difference if you power it through Pi-2 bus as opposed to Euler bus?

Also, where is that jumper that is supposed to provide extra mAh power to USB ports when the board is powered through GPIO?

Shouldn't be any difference whatsoever from what I can tell... since the euler DCIN is connected to the Pi2 5v Smile

As for the jumper, I have no idea... But since the schematic seems to indicate that the VCC-5V line is connected to the USB-5V, if you put 5v down the 5v euler pin then whatever current your power supply can provide should be available to the devices on the USB... then again, my multimeter doesn't seem to agree with me!

I'm in the process of making a USB to PST cable to power the board via the Euler bus.

I had read somewhere that there's some kind of jumper which supposedly lets more power through the USB ports than the max. 680mAh that the board can provide if powered via micro USB. 

Given that the maximum current micro USB protocol allows is 1.8A,  from what I understand, powering the board via the pins, automatically increases current (>680mAh) to the boards USB ports. That's what I'm after. I want to power a USB 2.0 drive.

Thanks a lot.
