Below, for you to explain the Win7 U disk letter does not show the solution.
First, go to the "Computer" management menu. With the right mouse button "Computer", select "Management" to enter the Computer Management interface.
Second, in the Computer Management interface to select Disk Management, here, we can clearly see that there is a "removable" disk. This is what we are looking for the U disk, careful we can find that the "removable" disk just does not have disk symbols. Of course, all we need to do is to add disk symbols to the USB drive.
Third, in the interface to select the Pocket U disk PE, right click to change the drive letter and path, as shown in the following figure.
Click the Add button to go to the next step.
