The V400m Plus 3G & V400m Bases has a couple of USB cabling scenarios:
• Direct USB Connection
• Powered USB Connection
Direct USB
Connection
Similarly, a USB cable (VPN - CBL282-038-XX-A) is required in standard USB
environments. For this cable option, the host end has a molded housing which
exposes the standard USB plug.

A Powered USB cable allows for devices to obtain power through their USB host
instead of requiring an independent power supply or external AC adapter.
Connect the cable (VPN - CBL282-033-01-A) to the V400m Plus 3G & V400m
Bases and plug the male USB connector into the corresponding USB port of the
connecting device.
