| 摘要 |
Various embodiments enable a host controller, through its Protocol Adaption Layer (PAL) driver, to efficiently manage power consumption by employing “sleep mode” and “active mode” power settings. In some embodiments, the PAL driver may employ sleep mode settings to transition the host controller from an idle state to an energy conserving sleep state. In further embodiments, the PAL driver may use active mode settings to govern communications between the host controller and various devices, such as WUSB devices and others, thereby conserving power.
