A data transmission bridge device for transmitting data that adheres to USB specification for transmitting data and includes: a first connecting interface, a second connecting interface, and a control chip. The first connecting interface is used for connecting a first host device, and the second connecting interface is used for connecting a second host device or a slave device. The control chip connects the first connecting interface and the second connecting interface, and further includes two transmission paths. The control chip detects which device is connecting to the second connecting interface, and switch to select one of the two transmission paths for transmitting data between the first connecting interface and the second connecting interface. Therefore, the present invention can achieve the purpose that the host device can bridge and transmit data with any other device conveniently.
