This Transform controls an Electro Standards 4506 PathWay USB Type A Switch. The switch provides the capability of sharing a single USB interface device connected to the common port among two or three other devices connected to the A, B, and C USB ports.
0 = Invalid command
1 = USB A
2 = USB B
3 = USB C
The value of the Command port (on the Transform) controls which USB (hardware) port is connected through the switch.
The Response port is a message port. When the status of the switch changes a message is transmitted.
