The FreeRunner's USB port can be switched from device to host separately
on the data and power pins, so my guess is that you set its data pins to
host mode but left the power in device mode, which means that the FR
will not provide power via USB but will expect to pull power from it
instead (this is typically used together with a tweaked USB hub powered
from a power brick).
