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.
