Abstract

In one or more embodiments, a bus driver, included on a local computing system, enables detection of hardware available on a host computing system for a remote access session. Upon detecting a hardware device on the host computing system, an operating system included in the local computing system may obtain a device driver for controlling data captured from the hardware device. The device driver may be used to inject data captured from the hardware device into the local operating system'"'"'s input stack. In some examples, the data is injected into the local operating system'"'"'s input stack at a layer that corresponds to a layer at which the data was captured on the host computing system.

Claims

1. A method comprising:

sending a bus signature that makes a local operating system aware of a hardware device detected on a host computing system, the bus signature being sent from a bus driver within the local operating system; and

obtaining a device driver to control data captured from the hardware device for the local operating system.

2. The method of claim 1, further comprising injecting the data into the local operating system'"'"'s input stack at a layer that corresponds to a particular said layer at which the data was captured.

3. The method of claim 1, wherein the hardware device is a digitizer.

4. The method of claim 3, wherein the device driver is configured for use with one or more of a contact input device or a microphone.

5. The method of claim 1, wherein the device driver is obtained from at least one of a third party provider or local memory.

6. The method of claim 1, wherein the bus signature is plug-and-play compliant.

7. The method of claim 1, further comprising injecting the data into the local operating system'"'"'s input stack at lowest most layer of the local operating system'"'"'s input stack.

8. The method of claim 1, further comprising when a data packet is not received within an allotted time or when a data packet having limited amount of data in comparison to a previous data packet is received, recreating data using data from the previous data packet.

9. A system comprising:

a bus driver to send a bus signature of a hardware device detected on a host computing system; and

an operating system to obtain a device driver that corresponds to the bus signature to control data captured from the hardware device for the operating system.

10. The system of claim 9, wherein the hardware device is a digitizer.

11. The system of claim 9, wherein the bus signature is plug-and-play compliant.

12. The system of claim 9, wherein the device driver is further configured to inject the data into the operating system'"'"'s input stack at a layer that corresponds to a particular said layer at which the data was captured.

13. The system of claim 12, wherein the data is injected into the operating system'"'"'s input stack at a lowest most layer of the operating system'"'"'s input stack.

14. The system of claim 9, wherein the device driver is further configured to when a data packet is not received within an allotted time or when a data packet having limited amount of data in comparison to a previous data packet is received, recreate data using data from the previous data packet.

15. One or more computer-readable media comprising instructions that are executable to provide a bus driver that:

forms a communication to send a bus signature that corresponds to a hardware device detected on a host computing system; and

injects data captured from the hardware device into an operating system input stack at a layer that corresponds to a layer at which the data was captured at the host computing system.

16. One or more computer-readable media as described in claim 15, wherein the data is injected into the operating system input stack at a lowest most layer of the operating system input stack.

17. One or more computer-readable media as described in claim 15, wherein the data is injected into the operating system input stack at a driver layer of the operating system input stack.

18. One or more computer-readable media as described in claim 15, wherein the bus signature is plug-and-play compliant.

19. One or more computer-readable media as described in claim 15, wherein the hardware device is a digitizer.

20. One or more computer-readable media as described in claim 15, wherein the instructions are further executable to when a data packet is not received within an allotted time or when a data packet having limited amount of data in comparison to a previous data packet is received, recreate data using data from the previous data packet.
