standards. The approximate USB bus speeds are shown in the following table.

Bus

Speed/Second

USB 1.1

12 Mbits

USB 2.0

480 Mbits

Actual bus speeds can vary, depending on the CPU speed, memory, speed of the network,

and other variables. The modem router should work with USB 2.0-compliant or 1.1-compliant

external flash and hard drives. For the most up-to-date list of USB drives supported by the

modem router, go to

.

When selecting a USB device, bear in mind the following:

•

The USB port on the modem router can be used with one USB hard drive at a time. Do

not attempt to use a USB hub attached to the USB port.

•

According to the USB 2.0 specification, the maximum available power is 5V @ 0.5A. If a

USB device exceeds this requirement, it might not function or might function erratically.

Check the documentation for your USB device to be sure.

•

The modem router supports FAT, FAT32, NTFS (read only), and NTFS with compression

format enabled (read only).

File-Sharing Scenarios

You can share files on the USB drive for a wide variety of business and recreational

purposes.

You can create your own central storage location for photos and multimedia. This eliminates

the need to log in to (and pay for) an external photo-sharing site.

1.

Insert your USB drive into the USB port on the modem router either directly or with a

USB cable.

Computers on your local area network (LAN) can access this USB drive using a Web

browser or Microsoft networking.
