But you can try this:


1- Open Windows Explorer

2- Go to C:/Windows/System32/DriverStore

You will have a couple of folders and files.
You will have *.dat files and other file named: infcache.1

3- Right click every file (dont touch the folders!) and choose properties.

4- go to security tab

5- click Edit

6- choose your account and check the box: full control (see ss)

7- Click ok.

8- Repeat to every file

9- Select all the files (*.dat and infcache.1)

10- Press shift+del

11- Press OK.

12- Now, go to C:Windows/System32/Driver Store/File Repository/

13- Search for folder named usbstor.inf

14- Open it (if you have more than one, choose the most recent)

15- Copy "usbstor.inf" and "usbstor.PNF"

16- Paste those two files to C:/Windows/inf

17- Reboot your pc and voilla! :b

If Windows doesnt install them automatically go to device manager, uninstall all unknown devices and the ones with the yellow exclamation mark, then click on "check to see if there is any hardware changes"
