1. A method comprising:
- while operating a device in accordance with a current operating power state, receiving a power control command from a host connected to the device;
in response to receiving the power control command, dynamically modifying mapping information in the device based on the power control command, the mapping information comprising mappings between device power management commands and device operating power states;
receiving a device power management command to transition the operation of the device to a specified operating power state;
based on the specified operating power state in the device power management command and the mapping information, determining a new operating power state for the device; and
operating the device in accordance with the new operating power state, wherein the new operating power state is different than the specified operating power state.
