Unable to install USB driver in Windows7

Asked By 0 points N/A Posted on -

Hi all,

I am using HP – 215 G1 Pro (11.6" Touchscreen Laptop – AMD A4-Series – 4GB Memory – 320GB Hard Drive – Silver) laptop with Windows7 and it is all fine.

But I am facing an issue while installing USB drivers for my Samsung GT 7580. It is taking a long time, but couldn't install the drivers needed. I have tried several ways. I have uninstalled and installed drivers after downloading manually, but no use. I have tried updating my phone driver, but it is failing with an error that windows encountered an error while attempting installing it. I am not sure what is going on here.

Anybody faced this issue before? Please help me. Thanks!

You can fix this problem using Windows 4 64 bit but you must have all administrator privileges. 

1. Open the browser.

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

You will see *.dat files and other file named: infcache.1

3- Right click every file (don't 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 the same procedure 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/info

17- Reboot your pc and Voilla!

If Windows doesn't install them automatically go to device manager, uninstall all unknown devices and the ones with the yellow exclamation mark, then click in "check to see if there is any hardware changes"

Now, Windows will install all your hardware successfully
