Profile caching for a peripheral device

A keyboard device comprising:

• one or more processors;
• one or more non-transitory, computer-readable storage mediums containing instructions configured to cause the one or more processors to perform operations including:
• receiving, by the one or more processors from a host computing device communicatively coupled thereto, a request to switch to a first key input profile for a plurality of keys on the keyboard device;
• determining whether the first key input profile is locally stored on the keyboard device in a persistent memory;
• in response to determining that the first key input profile is stored in persistent memory, programming the plurality of keys using the first key input profile stored in the persistent memory;
• and
• in response to determining that the first key input profile is not stored in persistent memory:
• writing the first key input profile to persistent memory when the first key input profile is at least n bytes in size and programming the plurality of keys using the first key input profile,
• wherein the request to switch the first key input profile for the plurality of keys on the keyboard device includes a first hash code that represents the first key input profile, and
• wherein determining whether the first key input profile is locally stored on the keyboard device in the persistent memory is based on matching the first hash code with any other hash codes of the key input profiles stored in the persistent memory.

A non-transitory computer-program product tangibly embodied in a machine-readable non-transitory storage medium that includes instructions configured to cause one or more processors of a keyboard device to perform operations including:

• receiving, by the one or more processors from a host computing device communicatively coupled thereto, a request to switch to a first key input profile for a plurality of keys on the keyboard device;
• determining whether the first key input profile is locally stored on the keyboard device in a persistent memory;
• in response to determining that the first key input profile is stored in persistent memory, programming the plurality of keys using the first key input profile stored in the persistent memory;
• and
• in response to determining that the first key input profile is not stored in persistent memory:
• writing the first key input profile to persistent memory when the first key input profile is at least n bytes in size and programming the plurality of keys using the first key input profile
• wherein the request to switch the first key input profile for the plurality of keys on the keyboard device includes a first hash code that represents the first key input profile, and
• wherein determining whether the first key input profile is locally stored on the keyboard device in the persistent memory is based on matching the first hash code with any other hash codes of the key input profiles stored in the persistent memory.
