Solve the problem that Win7 can't be used again after exiting U disk

After her U disk found that the computer exited, she inserted the USB flash drive again and found that Windows 7 could not recognize the USB flash drive. You must restart your computer to recognize it again. What is the problem? Let's solve this problem:
Click on the Windows 7 desktop mouse and click on “Computer” to select “Attributes”. Click on the "Device Manager" in the top left corner, and then pop up "Device Manager" window, click to expand "Universal Serial Bus Control", there are many rows of "USB Root Hub" device list, I am here There are as many as eight. Right-click each "USB Root Hub", select “Disable” menu, then “Enable”.

This will be done in such a way that each USB remote hub will be able to recognize the USB flash drive again without rebooting.
