Good question ... The hardware used for the UBlocker - LAN or LAN/WiFi version are mini-computers also known as Raspberry Pi boards. The hardware vendors for these mini computers manufactured them with 4 USB ports and also a HDMI port - none of which are used by our application except for 1 USB port.
Why are there 4 USB ports on my Ultimate Call Blocker when only 1 USB port is used? Print
