The storage module 210 is accessed (step 511). As shown in FIG. 2A, the portable storage device 200 is an external storage medium connected to the computer, so that the user can operate the computer to access the first data in the portable storage device 200, that is, the computer can pass through The first transmission interface 220 transmits the new first data to the storage module 210, or reads the first data stored in the storage module 210 through the first transmission interface 220. The control module 250 on the portable storage device 200 may continue to determine whether the second transmission interface 230 is connected to the digital device because it does not detect that the second transmission interface 230 has a digital device connection (step 520).

If the mobile phone (the second digital device 302) is inserted into the USB slot on the mobile phone with the second transmission interface 230 before or after the portable storage device 200 is inserted into the USB slot on the computer with the first transmission interface 220, The storage device 200 inserts the first transmission interface 220 into the USB slot on the computer (step 511), that is, the second transmission interface 220 in the portable storage device 200 provides access to the mobile phone after being connected to the mobile phone. The first data in the storage module 210 is stored (step 512).

No matter whether the portable storage device 200 is connected to the computer and then connected to the mobile phone, or connected to the mobile phone and then connected to the computer, after the first transmission interface 220 is connected to the computer and the second transmission interface 230 is connected with the mobile phone, the portable storage device 200 The control module 250 determines that the portable storage device 200 is simultaneously connected to the computer and the mobile phone (step 520). Thereafter, the control module 250 creates a virtual data transmission channel 260 as shown in FIG. 2B.

After the control module 250 establishes the data transmission channel 260 between the first transmission interface 220 and the second transmission interface 230, the operating system executed on the computer knows that there is a new digital device (ie, a mobile phone) through the USB slot. Connected to the computer, the computer can access the second data on the mobile phone through the portable storage device 200, and the portable storage device 200 transmits the second data on the mobile phone to the computer or transmits the second data in the computer to the mobile phone (step 530). . On the contrary, the mobile phone can also access the second data in the computer through the portable storage device 200, so that the portable storage device 200 can become a data transmission carrier between the computer and the mobile phone.

In summary, it can be seen that the difference between the present invention and the prior art is that the portable storage device can provide the first digital device and the second digital device to access the first data, and simultaneously carry the first digital device and the second digital device with the portable device. When the storage device is connected, the first digital device and the second digital device are provided to transmit data to each other, and the technical means can solve the problem that the prior art has a complicated process of using the portable storage device as a data transmission carrier, thereby achieving convenience.

In addition, if the mobile phone needs to be accessed through a special application, or the computer needs to install a driver to access the mobile phone, the control module 250 determines that the first digital device is connected to the second digital device at the same time (step 520). The portable storage device 200 can read the corresponding program through the second transmission interface 230 to the mobile phone and transmit the corresponding program to the computer through the first transmission interface 220. The program read by the portable storage device 200 includes but is not limited to the application that the computer needs to execute. The program or the driver that needs to be installed.

After receiving the program transmitted by the portable storage device 200, the computer executes the received program. When the computer wants to access the data on the mobile phone, the control signal generated by the program executed on the computer generates a request for transmission. After the storage device 200 is delivered to the mobile phone, the second data to be accessed is transmitted (step 530).
