A high-speed scalable backplane enables communications between a central processing unit (CPU) module and field input/output (I/O) and/or communication modules. The backplane comprises a root hub associated with the CPU module. The backplane also includes a plurality of Universal Serial Bus (USB) hubs sequentially coupled to each other and arranged according to the tiered architecture. Each of the USB hubs has an upstream port and a plurality of downstream ports. A top USB hub has an upstream port coupled to a host port of the root hub. One or more lower USB hubs each have an upstream port coupled to a selected downstream port of one of the USB hubs in an immediately preceding tier of the tiered architecture. The lower USB hubs are each configured to enable a plurality of I/O and/or communications connections for the modules via a plurality of downstream ports.
