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.
