Hardware assisted endpoint idleness detection for USB host controllers

An electronic apparatus, comprising:

• at least one memory module;
• a universal serial bus (USB) host controller coupled to the memory module, wherein the USB host controller implements hardware assisted idleness endpoint detection, wherein the host controller comprises logic to:
• execute a transaction at the endpoint;
• define an idleness threshold parameter for the endpoint;
• set an idleness count bit equal to the idleness threshold parameter when the transaction at the endpoint is completed;
• and
• decrement the idleness count bit when a microframe passes without successful data transmission from the endpoint.
