Discovery mechanisms for universal serial bus (USB) protocol adaptation layer

1. An apparatus comprising:

memory; and

processing circuitry configured to:

provide service information during Wi-Fi Serial Bus (WSB) discovery, the service information including a parameter to indicate a version of the universal serial bus (USB) specification supported by the apparatus;

wherein the apparatus is a first apparatus, and the processing circuitry is further configured to wirelessly establish a Wi-Fi connection to a second apparatus, based on the version in the service information, at a link layer in a Wi-Fi Peer-to-Peer (Wi-Fi P2P) group, to establish a WSB connection over the Wi-Fi connection; and

perform USB device communications over the Wi-Fi connection, after the WSB connection being established.

2. The apparatus of claim 1 , wherein the processing circuitry has further logic to generate a signal to indicate whether the apparatus supports Internet Protocol (IP) transport.

3. The apparatus of claim 1 , wherein the service information includes a user friendly description to identify the apparatus.

4. The apparatus of claim 1 , wherein the processing circuitry includes logic to provide WSB architectural element service information, wherein the WSB architectural element service information indicates whether the apparatus is a WSB Host, a WSB Hub, or a WSB Peripheral.

5. The apparatus of claim 1 , wherein the processing circuitry is configured to identify the apparatus as a P2P Group Owner.

6. The apparatus of claim 1 , further including a signal generation device.

7. The apparatus of claim 1 , further including a touch screen.

8. The apparatus of claim 1 , further including two or more antennas.

9. The apparatus of claim 1 , wherein the apparatus is configured to operate using a near field communication (NFC) protocol.

10. A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of a Wi-Fi Serial Bus (WSB) device to perform operations comprising:

respond to a probe request frame from at least one other WSB device in a Wi-Fi Peer-to-Peer (Wi-Fi P2P) group;

provide service information subsequently to responding to the probe request frame, the service information including a parameter to indicate a version of the universal serial bus (USB) specification supported by the WSB device;

establish a WSB connection with the at least one other WSB device based on the service information; and

perform USB device communications over the Wi-Fi connection, upon the WSB connection being established.

11. The non-transitory computer-readable storage medium of claim 10 , wherein the WSB device is a P2P Group Owner.

12. The non-transitory computer-readable storage medium of claim 10 , wherein the Wi-Fi P2P group operates at a frequency band higher than 45 gigahertz (GHz).

13. A Wi-Fi Serial Bus (WSB) device comprising:

a network interface device, a processor, and a memory, the network interface device to:

provide service information during WSB discovery, the service information including a parameter to indicate a version of the universal serial bus (USB) specification supported by the WSB device;

wirelessly establish a Wi-Fi connection to at least one other WSB device, based on the service information, at the link layer in a Wi-Fi Peer-to-Peer (Wi-Fi P2P) group, to establish a WSB connection over the Wi-Fi connection; and

perform USB device communications over the Wi-Fi connection, upon the WSB connection being established.

14. The WSB device of claim 13 , wherein the service information is provided subsequently to performing a P2P probe request and P2P probe response exchange.

15. The WSB device of claim 13 , further comprising two or more antennas.

16. The WSB device of claim 13 , further comprising signal generation circuitry to generate a signal to indicate whether the WSB device supports Internet Protocol (IP) transport.

17. The WSB device of claim 13 , wherein the WSB device is configured to operate at frequencies greater than 45 gigahertz (GHz).
