Each lower portion of the PoweredUSB port provides +5V @ 500mA. If more than 500mA are drawn
from a port, that port goes into USB over current, the +5 volts is turned off, and the condition is
reported to the host according to USB 2.0 specifications.

occurs, unplug the DC connection, remove the overcurrent condition, and re-cycle the DC
connection to the Hub by unplugging it, and then plugging it in again.
