Abstract: The present invention discloses a Universal Serial Bus (“USB”) device that includes an Ethernet port configured to receive a first Ethernet packet, and an input control circuit including a data register memory, a header register memory and an input data control circuit. The input data control circuit, upon receiving a first Ethernet packet, stores first packet data of the first Ethernet packet in the data register memory, transmits the first packet data to a USB host, and, in response to the transmission of the first packet data, stores first header data of the first Ethernet packet in the header register memory.

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.

Abstract: A hybrid serial peripheral interface (SPI) data transmission architecture adapted in a network device for connecting a host and a network is provided. The architecture comprises a RX buffer and RX SPI for maintaining a data receiving process, a TX buffer and TX SPI for maintaining a data transmission process, a configuration and status register and a hybrid SPI processing module. The hybrid SPI processing module makes the RX SPI performs the data transmission process as well when the RX SPI idles and the data transmission process proceeds at the same time and makes the TX SPI to performs the data receiving process as well when the TX SPI idles and the data receiving process proceeds at the same time. A hybrid SPI data transmission method is disclosed herein as well.

Abstract: A bulk transfer control method of a universal serial bus (USB) device includes a timer for counting transmission time of a buck transfer. When the transmission time counted reaches a transmission time setting value, a trigger signal is issued to a transfer end event generator. Then, the transfer end event generator issues a transfer end event signal to a data processing unit so as to end the bulk transfer. Moreover, a USB device and its bulk transfer control circuit are also provided.
