Abstract

Management of data communication between a peripheral device and host computer system is provided. A peripheral device exposes to a host computer system multiple interfaces for data communication between the peripheral device and the host computer system. The multiple interfaces are exposed over a single physical interface between the peripheral device and the host computer system, for communicating data between the peripheral device and multiple applications executing on the host computer system. The multiple interfaces can include a data collection interface facilitating collection of data from the peripheral device by an application of the multiple applications executing on the host computer system.

Claims

1. A method for managing data communication between a peripheral device and a host computer system, the method comprising:

exposing to the host computer system, by a processor of the peripheral device, multiple interfaces for data communication between the peripheral device and the host computer system, the multiple interfaces being exposed over a single physical interface between the peripheral device and the host computer system, the multiple interfaces for communicating data between the peripheral device and multiple applications executing on the host computer system, wherein the multiple interfaces comprise a data collection interface facilitating collection of data from the peripheral device by an application of the multiple applications executing on the host computer system;

wherein the data collection interface collects barcode data for provision to the application of the multiple applications executing on the host computer system.

2. The method of claim 1, wherein the data collection interface comprises a line of business interface for data communication between the peripheral device and a line of business application of the multiple applications.

3. The method of claim 1, wherein the single physical interface comprises a Universal Serial Bus interface.

4. The method of claim 3, wherein the peripheral device behaves as a Universal Serial Bus composite device exposing the multiple interfaces responsive to a Universal Serial Bus host enumeration request.

5. The method of claim 1, wherein at least one interface of the multiple interfaces comprises a Universal Serial Bus Human Interface Device class interface, wherein the peripheral device exposes the Universal Serial Bus Human Interface Device class interface as having a non-standard configuration so as to be ignored by the application of the multiple applications executing on the host computer system.

6. The method of claim 5, wherein the non-standard configuration comprises a non-standard usage page number of the Universal Serial Bus Human Interface Device class interface.

7. The method of claim 1, further comprising receiving commands by the peripheral device from the host computer system across the multiple interfaces and responding to the received commands, wherein the peripheral device, in responding to a command, responds to the command across a same interface of the multiple interfaces through which the command was received from the host computer.

8. The method of claim 7, wherein the peripheral device is configured to give priority to one interface of the multiple interfaces, responsive to contemporaneously receiving more than one command across more than one interface of the multiple interfaces.

9. The method of claim 8, wherein priority is given to the data collection interface of the multiple interfaces over at least one other interface of the multiple interfaces.

10. The method of claim 1, wherein the peripheral device is selectably configurable to exclusively use of one interface of the multiple interfaces to facilitate performance of at least one of:

a firmware upgrade, or a peripheral device reconfiguration.

11. The method of claim 10, wherein exclusive use of one interface of the multiple interfaces comprises one of temporarily blocking requests through other interfaces of the multiple interfaces through the period of exclusive use of the one interface, or temporarily queuing requests through other interfaces of the multiple interfaces through the period of exclusive use of the one interface.

12. The method of claim 1, wherein the peripheral device is selectably configurable to expose any one or more of the multiple interfaces to the host computer system.

13. The method of claim 1, wherein the peripheral device is configurable to recognize commands received through another interface of the multiple interfaces as being valid, wherein the commands are not recognized as being valid if received through the data collection interface.

14. The method of claim 1, wherein the single physical interface comprises at least one of:

a Bluetooth interface, a WiFi interface, or a ZigBee interface.

15. The method of claim 1, wherein the peripheral device comprises an encoded information reading device configured to output a decoded message, wherein data communicated from the peripheral device to the application comprises the decoded message.
