USB devices, that is, the external devices of our win7 64-bit flagship download system, are actually used very frequently in our daily operations, such as our U disk, mobile hard disk, external drives, printer and so on. These are USB devices, and some devices that we often operate in our daily operations. Generally speaking, it is very simple for us to use USB devices in win7 flagship computer, as long as we plug them directly into the USB interface of win7 flagship computer. Recently, however, a user using win7 flagship computer asked that the driver installation failed after his USB device was plugged in. So how can we solve this problem? Below, Bian Xiao will introduce it in detail!

1. First, let's go back to the desktop location of the win7 Ultimate PC. Then, let's find the computer icon on the desktop and click E-mail. In the drop-down menu that appears, let's select the device manager option.

2. In the device manager window of win7 Ultimate PC, we found the USB device marked with exclamation mark in the left pane, then right-click and select Update Driver. Note that you can't choose automatic search here. You should choose to set the installation location, and then change the address to c:/windows/winsxs in the file selection here.

3. There will be an early warning prompt later, that is, you have installed an unsigned file or something, so we choose to continue the installation and wait for the installation to be completed.
