摘要： A USB switching device can selectively connect between a removable card and a mobile wireless communication device and a computer. The removable card has a first port; the mobile wireless communicating device has a second port while the computer has a third port. The switching device comprises a first full duplex switch having an input and a first output and a second output, and a select port for switching the connection of the input to the first output and the connection of the input to the second output. The switching device further comprises a second full duplex switch having an input and a first output and a second output, and a select port for switching the connection of the input to the first output and the connection of the input to the second output. The switching device further comprises a third full duplex switch having an input and a first output and a second output, and a select port for switching the connection of the input to the first output and the connection of the input to the second output. The input of the first switch is connected to the first port. The input of the second switch is connected to the second port. The input of the third switch is connected to the third port. The first output of the first switch is connected to the second output of the second switch. The second output of the first switch is connected to the first output of the third switch. Finally, the first output of the second switch is connected to the second output of the third switch.
