Abstract

The invention provides a data transmission device and a method thereof. The data transmission device comprises a first interface, a second interface and a converter, wherein the first interface is used for connecting a master device; the second interface is used for connecting a USB storage device; the converter is connected between the first interface and the second interface, is internally provided with a power supply for supplying power for the master device and the USB storage device respectively through the first and the second interfaces; and the converter is used for transmitting data between the first and the second interfaces. The data transmission device and the method thereof can realize the data transmission between devices since the converter is arranged and is used for supplying power for the two devices; and the data transmission device is convenient for carrying.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data transmission, and in particular, to a data transmission device and method. Background technique [0002] Digital products have become more and more important in people's lives. For example, high-tech digital products such as digital cameras, mobile phones, and MP3 players have become an important part of people's lives, and mobile phones have become a necessity for people's lives. These devices can generally communicate with a computer. Taking a mobile phone as an example, the mobile phone can perform data transmission with the computer. During data transmission, the computer acts as the master device, and the mobile phone acts as the slave device, and the computer supplies power to the mobile phone to support data transmission between the two. However, the computer has the disadvantage of being inconvenient to carry around, which makes it impossible to carry out data commu...
