  • Publication number: 20130145191
    Abstract: The present invention discloses a Universal Serial Bus (“USB”) device with a power saving mechanism. The USB device includes an Ethernet physical layer, a USB physical layer, a wakeup packet detection circuit configured to receive a wakeup packet from the Ethernet physical layer, and a standby power saving control circuit. The standby power saving control circuits selects a connection speed from the group including EEE, 10 Mbps, 100 Mbps, 1 Gbps and 10 Gbps, wherein the standby power saving control circuit is able to connect to a wakeup device at the selected connection speed, so that the USB system can enter an optimal power saving status while in a standby mode. The connection speeds are defined in the specification of IEEE 802.3az as 10BASE-T, 100BASE-TX, 1000BASE-T, 10GBASE-T, 1000BASE-KX, 10GBASE-KX4, 10GBASE-KR.

  • Publication number: 20130145186
    Abstract: The present invention discloses a Universal Serial Bus (“USB”) device capable of remote wake-up through a special mask circuit. The USB device includes an Ethernet port to transmit a first signal in response to a predetermined network packet, a wake-up pin to transmit a second signal in response to a remote wake-up trigger signal, a remote wake-up circuit to generate a wake-up signal in response to either the first signal or the second signal, and a mask circuit to receive the wake-up signal and delay transmission of the wake-up signal to a remote USB host for a predetermined delay time.
