DISTRIBUTED CONTROL OF DEVICES USING DISCRETE DEVICE INTERFACES OVER SINGLE SHARED INPUT/OUTPUT
First Claim
1. A method, comprising the steps of:
- providing a plurality of virtual device interfaces for a device, wherein each virtual device interface enables client control of a discrete function of the device; and
controlling concurrent communication between the device and two or more virtual device interfaces operating on a single shared I/O connection using a device input/output (I/O) interface.

Abstract
Systems and methods are provided for controlling a device. In one aspect, a method for controlling a device includes exposing a plurality of virtual device interfaces (13) for a device (11), wherein each virtual device interface (13) enables client control of a discrete function of the device, and controlling concurrent communication between the device (11) and two or more virtual device interfaces (13) operating on a single shared I/O connection (15) using a shared I/O port controlled by a device I/O module (12). The device I/O module (12) enables independent development of multiple device interfaces (13) that can seamlessly and independently operate on a single (physical) device communication connection (15), wherein the device shared I/O (input/output) module (12) implements functions to arbitrate and coordinate I/O activity between the device interfaces (13) and target device (11).
