Abstract

A data transmitting method for communicating one of a plurality of portable devices with a host computer via a data transmitting device having a plurality of USB connector is disclosed. In one embodiment of the present invention, the method includes the following steps: firstly, a switch circuit is configured in one of the portable devices. Then, the portable device having the switch circuit is coupled with the data transmitting device. Afterward, a data transmission path between the host computer and the portable device having the switch circuit is connected by the switch circuit to transmit data between the portable device having the switch circuit and the host computer, or the data transmission path between the USB connector, which is not connecting with the portable device having the switch circuit, and the host computer is connected by the switch circuit.

Description

technical field [0001] The invention relates to a data transmission device and system, in particular to a data transmission device, system and method for communicating with a portable device. Background technique [0002] Handheld Devices or Portable Devices, such as flash drives, can not only be used to transmit data, but also can usually be charged by being plugged into an interface connection port of a computer, such as a USB connection port. However, the number of interface connection ports on the computer is limited. In order to allow more handheld devices to communicate with the computer, a USB hub has been developed to connect the handheld device and the computer. [0003] Please refer to figure 1 , which is a schematic structural diagram of a data transmission system of a conventional portable device. The data transmission system 1 for portable devices includes a computer host 11 and a USB hub (USB Hub) 13 . The USB hub 13 has a plurality of sub-ports 131 for plug...
