Windows 7: Unable to install any USB devices

Unable to install any USB devices

Hi guys,


Wonder if any of you fine folk can help me out. I noticed a problem with my Windows 7 64x not picking up new usb devices such as usb sticks, ones i already have used on the computer was working fine. Today I come home and find my keyboard isn't working but my mouse is (they are both connected by wireless). So after playing around with it for a while i uninstall my mouse and keyboard and reboot my computer. Windows 7 will now load to where i can select my home account. Only problem is Windows 7 is not picking up any of my USB devices so i am unable to click into my home account. I have even tried a few usb keybaords and a ps2 one. They keyboard do work in the bios and I have been unable to find any option that would disable usb devices. I have tried to recovery disk but TNA. I think i will end up reinstall Windows 7 but if anyone else have got ideas i am all ears.


Thanks in advance.

Thanks in advance.

Hey there! I had this same problem too! untill a while ago! It's very frustrating! I spent days on it! So, I will make your job easy by telling how to solve this. This was the way it worked for me!

Here's the solution for the ones who might have this problem:
This worked for me in Windows 7 Ultimate 64bit!
You must have all administrator privileges!


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 in "check to see if there is any hardware changes"

Now, Windows will install all your hardware successfully :b



Did it work?

Just like others, I just joined to say thank you.

I had tried several different "solutions" around the web for months and I was just about to give up and reinstall windows (which is a total pain with so much backing up to do) but I followed your steps and it worked! so thank you very much.
