USB expansion module method and design
First Claim
Patent Images
1. A system that facilitates expanding upon an existing universal serial bus (USB), comprising:
- a base component that includes a USB host to provide connectivity to at least one device;
an expansion module that physically connects in a vertical position to a backside of the base component without an intervening USB cable, the expansion module provides a replication of the USB host and allows an additional device to connect to the replicated USB host, wherein the expansion module is stackable with one or more additional expansion modules via at least one snap-foot without intervening USB cables; and
a key mechanism that is adjustable to physically prevents stacking an additional expansion module to a last expansion module in the stack when power draw from the stack is within a threshold range, wherein the keying mechanism is a connector that is turned to an orientation that prevents stacking the additional expansion module.

Abstract
The claimed subject matter provides a system and/or method that facilitates expanding upon an existing universal serial bus (USB). A base component can include a USB host to provide connectivity to at least one device. An expansion module can physically connect in a vertical position to a backside of the base component to provide a replication of the USB host which can allow a device to connect therewith.

16. A system that facilitates connecting devices, comprising:
-
a base unit with a USB port to provide connectivity to at least one device; an expansion module that attaches to a backside of the base unit via at least one snap-foot without an intervening cable, wherein the expansion module replicates the USB port for expansion to an additional device, wherein the expansion module has one or more connectors for one or more additional expansion modules to attach to the expansion module in a vertical stack without intervening cables between the expansion module and the one or more additional expansion modules, each additional expansion module provides an additional replication of the USB port, wherein the USB port, replicated USB port and additional replicated USB host are daisy-chained; and a key mechanism that adjustable to physically prevents stacking an additional expansion module to a last expansion module in the stack when power draw from the stack is within a threshold range, wherein the keying mechanism is a connector that is turned to an orientation that prevents stacking the additional expansion module. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)

24. A method that facilitates expanding upon an existing universal serial bus (USB), comprising:
-
vertically stacking at least two expansion modules onto a backside of a base component via at least one snap-foot without having an intervening cable between the base component and an expansion module, and without having an intervening cable between the at least two expansion modules, wherein the base component has a USB port; replicating the USB port on each of the at least two expansion modules, wherein the USB port and replicated USB ports are daisy-chained; and preventing stacking an additional expansion module to a last expansion module in the stack when power draw from the stack is within a threshold range by employing an key mechanism, wherein the keying mechanism is a connector that is turned to an orientation that prevents stacking the additional expansion module. - View Dependent Claims (25, 26, 27)

28. A computer-implemented system that facilitates expanding upon an existing universal serial bus (USB), comprising:
-
means for including a USB host that provides connectivity to at least one device on a base terminal human machine interface (HMI); means for physically connecting a plurality of expansion modules in a vertical stack to a backside of the base terminal HM! without having an intervening cable between the base component and an expansion module, and without having an intervening cable between the plurality of expansion modules, wherein each expansion module replicates the USB host, wherein the USB host and replicated USB hosts are daisy-chained; and means for managing power draw of the stack by employing a keying mechanism that is adjustable to physically prevents adding additional expansion modules to the stack that would result in a total power draw of the stack exceeding the power threshold, wherein the keying mechanism is a connector that is turned to an orientation that prevents stacking the additional expansion module.
