2.2 USB Cables

USB cables can have two different connectors. Type A connector is used to connect from
a USB device to the Type A port on a computer or hub. Type B connector is used to
attach the USB cable to a USB device. The Model UU-2X4 Sender has 2 Type B
connectors on it for connection to the PC(s).

2.3 Power Considerations

The Remote unit is set to supply 100mA max at each of its 8 outputs. This should be
enough for most USB devices. If your USB device requires more than 100ma of port
power for operation it would normally come with its own power supply.
