The MD400 is plugged in using the supplied extension cable or directly into a socket on the hub. The
hub configuration allows extended cable length so you can locate the MD400 for optimal reception.
Note:
Some powered hubs may not provide adequate power. Your hub must be capable of
supporting high power USB devices and must not be overloaded by the connection of too

and rechargeable music players. If you are experiencing problems, unplug these other devices
to test if your hub is overloaded.

Your MD400 is a USB 2.0 product, however it should work in the majority of USB 1.1 ports, but
