Overview

The US221A / US421A is a 2/4-port USB 2.0 Peripheral Switch

that allows up to 2/4 computers to share the use of a single USB

peripheral device (such as a printer, scanner, mass storage drive,

etc.*) on a one-at-a-time basis.

The peripheral focus can be given to a computer manually by

using pushbuttons on the switch or by using the software-based

configuration utility. In addition, the US221A / US421A has a new

Auto Switch function that stores commands sent to the USB

peripheral device to be processed on a first-come, first-served

basis, meaning that a print server is not required.

Compatible with both Windows and Mac, and with multifunction

printer support, the US221A / US421A is the ideal way to share

the latest USB 2.0 peripherals in a multimedia SOHO

environment.

Note: The US221A / US421A does not support a USB hub

peripheral device.
