The SiP VoIP and PoE Speaker adheres to the USB 2.0 electrical specifications as follows:
Standard USB 
lower A supply
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.
PoweredUSB 
supply
The listed maximum currents depend on the selected power supply. The +12V PoweredUSB ports 
are protected with active over current circuits. If an over current condition 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.
