From: Yonglong Wu <yonglong.wu@xxxxxxxxxxxx> In USB20 specification, describes in chapter 9.4.5: The Remote Wakeup field can be modified by the SetFeature() and ClearFeature() requests using the DEVICE_REMOTE_WAKEUP feature selector. In USB30 specification, also describes in chapter 9.4.5: The Function Remote Wakeup field can be modified by the SetFeature() requests using the FUNCTION_SUSPEND feature selector. In chapter 9.4.9 Set Feature reference, it describes Function Remote Wake Enabled/Disabled at suspend options by SET_FEATURE. In USB30 specification only mentioned SetFeature(), so we need use SET_FEATURE replace CLEAR_FEATURE to disable USB30 function remote wakeup in suspend options.
