A ICUSB232HUB2 provides bus-powered operation and does not require a power
adapter connection. Although an optional step, you may wish to use a 5V DC 1.2A
power adapter, to ensure that the peripherals connected to ICUSB232HUB2 receive
enough power. If you find that connected devices are performing poorly, this could be
the cause.
B Poor USB peripheral performance could be a result of the ports becoming overloaded.
Please remove and re-connect the USB HUB to the computer to refresh the ports.
