If I understand correctly, only below ports can be power off compared current's. - The internal port which is not connected any devices - The internal port which is connected non remote-wakeup featured device, and the port power can be off through user space application - any other ports? For fingerprint, how can we let it re-use? Unless there is another interrupt to indicate when we touch it or other things? > Sarah Sharp > -- > To unsubscribe from this list: send the line "unsubscribe linux-usb" in > the body of a message to majord...@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
