Sony Ericsson MD400 Modem User Manual


 
Overview 11
The USB port is in a position where physical pressure is put on the connector as shown
below.
Extension Cable
The extension cable provided is specially designed to work with your MD400. This is a high quality
USB cable that is capable of delivering high current to the MD400 when necessary. Using the cable
to distance your MD400 from your laptop will improve data speed/throughput performance.
Note:
Your MD400 may not operate correctly if you use a standard USB cable in place of the
provided extension cable.
Powered Hub
A self powered hub (not provided) may be used in conjunction with the extension cable and your
MD400. In some cases, especially when used with desktop PCs, it may be necessary to plug the
MD400 into a USB hub rather than directly into the PC. This is possible, provided that the hub is self
powered via its own AC adaptor.
Note:
It is not advisable to use a bus-powered hub with your MD400. These are hubs that have no
power supply of their own. Many portable hubs for laptops are of this type.
