Abstract

Examples of a competing device for universal serial bus data routing are disclosed. In one example implementation according to aspects of the present disclosure, a computing device may include one or more processors, a memory, and a data store. The computing device may also include a first universal serial bus (USB) connection port to communicatively couple an attached computing device to the host computing device, and a second USB connection port to communicatively couple a peripheral device to the host computing device. The computing device may further include a USB data routing module stored in the memory and executing on at least one of the one or more processors to route data between the attached computing device and the peripheral device via the host computing device.

First claim

What is claimed is:

1. A method comprising:
installing, by a host computing device, a universal serial bus (USB) data routing driver on the host computing device, the installing comprising installing the USB data routing driver stored in a memory of an attached computing device into the host computing device, the attached computing device communicatively coupled to the host computing device at a first USB interface, and the host computing device comprising a program launchable and useable by a user of the host computing device;
in response to user interaction with machine-readable instructions executed on the host computing device, accessing, by the machine-readable instructions, an operating system session of an operating system executed on the attached computing device;
receiving, by the USB data routing driver executed in the host computing device and installed from the memory of the attached computing device, a USB data message from the operating system session of the operating system executed on the attached computing device; and
routing, by the USB data routing driver executed in the host computing device, the USB data message received from the attached computing device at the first USB interface to a peripheral device communicatively coupled to the host computing device at a second USB interface.

2. The method of claim 1 , wherein installing the USB data routing driver on the host computing device includes modifying an existing USB driver on the host computing device to include the USB data routing driver.

3. The method of claim 1 , wherein installing the USB data routing driver on the host computing device is triggered by an installation module executed by the attached computing device communicatively coupled to the host computing device.

4. The method of claim 1 , further comprising:
receiving, by the USB data routing driver executed in the host computing device, a USB data message from the peripheral device via the second USB interface.

5. The method of claim 4 , further comprising:
routing, by the USB data routing driver executed in the host computing device, the USB data message received from the peripheral device via the second USB interface to the attached computing device via the first USB interface.

6. The method of claim 1 , wherein the USB data message routed from the first USB interface to the second USB interface remains in a same format and is unchanged by the host computing device.

7. A host computing device comprising:
a processor;
a memory;
a first universal serial bus (USB) connection port to communicatively couple an attached computing device to the host computing device;
a second USB connection port to communicatively couple a peripheral device to the host computing device;
a storage medium storing machine-readable instructions executable on the processor to, in response to user interaction with the machine-readable instructions, access an operating system session of an operating system executed on the attached computing device, and the storage medium storing a program launchable and useable by a user of the host computing device; and
a USB data routing driver stored in the memory by installing the USB data routing driver in the host computing device from a memory in the attached computing device, the USB data routing driver executable on the processor to route USB data from the operating system session of the operating system executed on the the attached computing device to the peripheral device.

8. The host computing device of claim 7 , wherein the machine-readable instructions comprise a web browser executable on the processor to access the operating system session of the operating system executed on the attached computing device in response to input of the user of the host computing device.

9. The host computing device of claim 7 , further comprising a USB controller to control the first USB connection port and the second USB connection port.

10. The host computing device of claim 7 , wherein the USB data routed from the first USB connection port to the second USB connection port remains in a same format and is unchanged by the host computing device.

11. The host computing device of claim 7 , wherein the first USB connection port and the second USB connection port are communicatively coupled to a single USB controller.

12. A non-transitory computer-readable storage medium storing instructions that, when executed cause a host computing device to:
install, in the host computing device, a universal serial bus (USB) data routing driver from a memory of an attached computing device communicatively coupled to the host computing device at a first USB interface;
in response to user interaction with a web browser executed on the host computing device, access, by the web browser, an operating system session of an operating system executed on the attached computing device;
receive, at the first USB interface, a first USB data message from the operating system session of the operating system executed on the attached computing device;
route, by the USB data routing driver executed in the host computing device and installed from the memory of the attached computing device, the first USB data message received from the attached computing device at the first USB interface to a peripheral device communicatively coupled to the host computing device at a second USB interface;
receive a second USB data message from the peripheral device at the second USB interface; and
route, by the USB data routing driver executed in the host computing device, the second USB data message to the attached computing device via the first USB interface.

13. The non-transitory computer-readable storage medium of claim 12 , further comprising instructions that cause the host computing device to:
install the USB data routing driver on the host computing device by installing the USB data routing driver from the memory of the attached computing device to a memory of the host computing device.

14. The method of claim 1 , wherein the installing of the USB data routing driver is in response to a command from the attached computing device.

15. The method of claim 1 , wherein the machine-readable instructions comprise a web browser, the method further comprising:
launching, at the host computing device, the web browser to communicate with the operating system session initiated by the operating system executed on the attached computing device, the web browser allowing the user to access the operating system session on the attached computing device.

16. The method of claim 1 , wherein the routing of the USB data message from the first USB interface to the second USB interface is performed without breaking apart the USB data message.

17. The host computing device of claim 7 , wherein the routing of the USB data from the first USB connection port to the second USB connection port is performed without breaking apart the USB data.

18. The non-transitory computer-readable storage medium of claim 12 , wherein the routing of the first USB data message from the first USB interface to the second USB interface is performed without breaking apart the first USB data message.
