2. Functional Overview

The GL620USB provides a single-chip solution for connecting two or more PCs via their USB ports. According

to USB protocol, the PC is the host and the device is a slave, where the host initiates all the USB traffic and the

slave responds to the host’s requests. In other words, a host cannot talk to another host via USB protocol; instead,

a host can only talk to one or more devices. The GL620USB’s patent-pending architecture overcomes the USB

inherently incompatibility of connecting two or more PCs by providing two independent USB transceivers and

SIEs for each host, i.e., data can be transferred in both directions simultaneously.
