Abstract: The present invention relates to a USB-based host-to-host networking method capable of transferring information between two hosts. Devices for the method comprise: a register, a pair of FIFO control command transmitters and at least one FIFO bulk transmitter. The register is to temporarily store control commands for information transaction and acts as a buffer. The control command transmitters is to connect two serial interface engines interfacing respectively with the USB interface of each host, by which the information transfer control commands can be delivered from either host. The bulk information transmitter connects to the two serial interface engines for bulk transfer so that any host is capable of issuing the information transfer control commands for executing data transaction between hosts. The present invention provides a new design for networking controller connection by reducing the number of control command transmitters needed, and also capable of transferring bulk information between hosts.

Abstract: A method and a related apparatus for controlling a transmission interface between a computer system and an external device is disclosed. The external device includes a bridge circuit for controlling the transmission interface of the external device, a driver circuit for controlling the external device according to outputs of the bridge circuit, and a memory connected to the driver circuit for storing transmission interface data. Before the computer system obtains the transmission interface data, the bridge circuit transmits a control command to the driver circuit such that the driver circuit retrieves the transmission interface data stored in the memory, and transmits the transmission interface data to the computer system such that the computer system can properly transmit data to the bridge circuit according to the transmission interface data.

Abstract: A portable storage device connects to a master computer and a first slave computer through a serial bus interface. The portable storage device contains a non-volatile memory for storing data in the portable storage device, a first slave port for connecting the portable storage device to the first slave computer through the serial bus interface, and a master port for connecting the portable storage device to the master computer through the serial bus interface. The master computer can access data located on the portable storage device and storage apparatuses of the first slave computer and the first slave computer cannot access any data located on the portable storage device and the master computer.

Abstract: A portable peripheral apparatus with an embedded storage module. The apparatus is connected to a computer via a communication interface, such as a USB interface or an IEEE 1394 interface. The portable peripheral apparatus includes a main device and an embedded storage module. The embedded storage module connects to the computer via the communication interface and has a storage device. The storage device stores peripheral data. If the storage device is a rewritable memory, then when receiving a specific instruction from the computer, the embedded storage module receives and updates the peripheral data stored in the storage device.
