Abstract

Claims (43)

1 . A game controller comprising:

at least one processor;

a non-transitory computer-readable medium; and

program instructions stored on the non-transitory computer-readable medium that, when executed by the at least one processor, cause the at least one processor to perform functions comprising:

receiving a plurality of requests from a host, wherein one of the plurality of requests comprises a request for a human interface device (HID) descriptor;

sending a single HID descriptor to the host, wherein the single HID descriptor comprises a first subset of information configured for a first operating system and a second subset of information configured for a second operating system;

analyzing the plurality of requests to determine which of the first and second operating systems is used by the host; and

selecting a mapping for user input elements of the game controller based on which of the first and second operating systems is determined to be used by the host.

2 . The game controller of claim 1 , wherein the plurality of requests are analyzed in response to receiving a request to get a HID report descriptor.

3 . The game controller of claim 1 , wherein the program instructions, when executed by the at least one processor, further cause the at least one processor to perform functions comprising:

receiving, from a game controller application running on the host, an identification of an operating system actually running on the host;

determining whether the selected mapping is configured for the operating system actually running on the host; and

in response to determining that the selected mapping is not configured for the operating system actually running on the host, using a different mapping.

4 . The game controller of claim 1 , wherein the program instructions, when executed by the at least one processor, further cause the at least one processor to perform functions comprising:

recording a setup packet for each of the plurality of requests in a history array.

5 . The game controller of claim 4 , wherein each setup packet comprises one or more of the following fields: bmRequestType, bRequest, wValue, wIndex, or wLength.

6 . The game controller of claim 4 , wherein requests that indicate that the host uses the first operation system or the second operating system are associated with unique identifiers and a list of unique identifiers is organized as a vector.

7 . The game controller of claim 1 , wherein the program instructions, when executed by the at least one processor, further cause the at least one processor to perform functions comprising:

selecting a default operating system in response to the analyzing being inclusive as to which of the first and second operating systems is used by the host.

8 . The game controller of claim 1 , further comprising a Universal Serial Bus (USB)-C connector configured to connect the game controller with the host.

9 . A method comprising:

performing in a universal serial bus (USB) device in communication with a host:

tracking a plurality of communications received from a host;

sending a hybrid human interface device (HID) descriptor to the host, wherein the hybrid HID descriptor comprises a plurality of subsets of information configured for a respective plurality of operating systems;

analyzing the plurality of communications to determine an operating system used by the host; and

selecting a usage map based on the operating system determined to be used by the host.

10 . The method of claim 9 , wherein the plurality of communications are analyzed in response to receiving a request to get a HID report descriptor.

11 . The method of claim 9 , further comprising:

updating the usage map in response to learning, from an application running on the host, that the host is using a different operating system.

12 . The method of claim 9 , wherein a presence of one or more of the following in the plurality of communications is indicative of the operating system used by the host: a request for a device qualifier descriptor, a request for a string descriptor, a specific sequence of a request for an audio interface and a request for a report descriptor, a request for a 64-byte get device descriptor, or a two-stage get device descriptor request.

13 . The method of claim 9 , wherein a presence of one or more of the following in the plurality of communications is indicative of the operating system used by the host: a get device qualifier request before a get configuration descriptor request, a get device qualifier request after a get configuration descriptor request, an absence of a device qualifier request before a get report descriptor request, a two-stage get string descriptor request, or a request for a 255-byte get string descriptor.

14 . The method of claim 9 , wherein a presence of one or more of the following in the plurality of communications is indicative of the operating system used by the host: a get configuration request before a get report descriptor request, a get string descriptor request before a get configuration descriptor request, an absence of a get string descriptor before a get configuration descriptor request, a set idle request before a get report descriptor request, or a request for a Microsoft operating system (MS OS) descriptor.

15 . A non-transitory computer-readable medium storing program instructions that, when executed by one or more processors in a mobile game controller, cause the one or more processors to perform functions comprising:

receiving a plurality of requests from the host;

sending a descriptor to the host, wherein the descriptor comprises a plurality of subsets of information configured for a respective plurality of operating systems;

analyzing the plurality of requests to determine an operating system used by the host; and

internally mapping various gamepad elements of the mobile game controller based on the operating system determined to be used by the host.

16 . The non-transitory computer-readable medium of claim 15 , wherein the descriptor comprises a human interface device (HID) descriptor.

17 . The non-transitory computer-readable medium of claim 16 , wherein the plurality of requests are analyzed in response to receiving a request to get a HID report descriptor.

18 . The non-transitory computer-readable medium of claim 15 , wherein the program instructions, when executed by one or more processors in the mobile game controller, further cause the one or more processors to perform functions comprising:

internally re-mapping the various gamepad elements of the mobile game controller based on learning an actual operating system used by the host.

19 . The non-transitory computer-readable medium of claim 15 , wherein the mobile game controller comprises a joystick, and wherein the mapping is for movement on a Y axis of the joystick.

20 . The non-transitory computer-readable medium of claim 15 , wherein the mobile game controller comprises a trigger, and wherein the mapping comprises an analog-to-digital conversion of a signal generated by actuation of the trigger.
