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, comprising:

exposing, using a processor of a peripheral device, multiple interfaces for data communication between the peripheral device and multiple applications executing on a host computer system over a single physical interface;

wherein the multiple applications executing on the host computer system comprise a management application; and

wherein the multiple interfaces comprise a dedicated management interface facilitating management of the peripheral device by the management application.

2. The method of claim 1, wherein:

the multiple applications executing on the host computer system comprise a line of business application;

the multiple interfaces comprise a line of business interface for data communication between the peripheral device and the line of business application; and

the dedicated management interface and the line of business interface are exposed separately to the host computer system to facilitate peripheral device management across the dedicated management interface in parallel with data collection across the line of business interface by the line of business application.

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

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

5. The method of claim 4, 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.

6. The method of claim 1, wherein the dedicated management interface comprises a Universal Serial Bus Human Interface Device class interface, the method comprising exposing, using a processor of the peripheral device, the Universal Serial Bus Human Interface Device class interface as having a non-standard configuration so as to be ignored by a line of business application of the multiple applications executing on the host computer system.

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

8. A method for managing data communication, comprising:

exposing, using a processor of a peripheral device, multiple interfaces for data communication between the peripheral device and multiple applications executing on a host computer system over a single physical interface;

receiving commands with the peripheral device from the host computer system across the multiple interfaces; and

responding to a received command, with the peripheral device, across a same interface of the multiple interfaces through which the command was received from the host computer system;

wherein the multiple applications executing on the host computer system comprise a management application; and

wherein the multiple interfaces comprise a dedicated management interface facilitating management of the peripheral device by the management application.

9. The method of claim 8, 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.

10. The method of claim 8, wherein priority is given to a data collection interface of the multiple interfaces over the dedicated management interface of the multiple interfaces, the data collection interface collecting barcode data for provision to a line of business application of the multiple applications executing on the host computer system.

11. The method of claim 8, comprising sending a notification over the dedicated management interface to the host computer system, wherein the notification is not made available across other interfaces of the multiple interfaces.

12. The method of claim 11, wherein the notification comprises barcode reading statistics.

13. The method of claim 11, wherein the notification comprises a low battery notification.

14. A method for managing data communication, comprising:

exposing, using a processor of a peripheral device, multiple interfaces for data communication between the peripheral device and multiple applications executing on a host computer system over a single physical interface;

wherein the multiple applications executing on the host computer system comprise a management application;

wherein the multiple interfaces comprise a dedicated management interface facilitating management of the peripheral device by the management application; and

wherein the peripheral device is selectably configurable to exclusively use one interface of the multiple interfaces to facilitate performance of a firmware upgrade and/or a peripheral device reconfiguration.

15. The method of claim 14, wherein exclusive use of one interface of the multiple interfaces comprises (i) temporarily blocking requests through other interfaces of the multiple interfaces through a period of exclusive use of the one interface or (ii) temporarily queuing requests through other interfaces of the multiple interfaces through a period of exclusive use of the one interface.

16. The method of claim 14, wherein the peripheral device is selectably configurable to expose any of the multiple interfaces to the host computer system.

17. The method of claim 16, wherein the peripheral device is selectably configurable to expose only the dedicated management interface to facilitate performance of a firmware upgrade and/or a peripheral device reconfiguration.

18. The method of claim 14, wherein:

the peripheral device is configurable to recognize commands received through the dedicated management interface as being valid; and

the commands are not recognized as being valid if received through other interfaces of the multiple interfaces.

19. The method of claim 14, wherein the single physical interface comprises a Bluetooth interface, a WiFi interface, and/or a ZigBee interface.

20. The method of claim 14, wherein:

the peripheral device comprises an encoded information reading device configured to output a decoded message;

data communicated between the peripheral device and the host computer system comprises the decoded message; and

the decoded message is communicated to a line of business application of the multiple applications executing on the host computer system.
