http://www.windowsreference.com/wind...vice-in-vista/

they mention infcache.1, that might be my prolem

please anyone help me? tried to delete the infcache.1 but no result...
also, I did this:

Open Regedit

Change HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
\DevicePath to '%SystemRoot%\System32'



also.. no results

lol I tried that, I restored my system to the oldest point I had! nothing changed...

HAHAAHAHAHAH FINALLY GUYS!!! I finally solved my problem! And no, I didn't need to re-install my Windows. As I thought, there had to be a way to solve this in a very easy way!

Finally I don't see this message again:

Windows found driver software for your device but encountered an error while attempting to install it.



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


Thank you all who tried to help me I'm really really happy now xD

P.S.- There should be a fix for this problem as it is a big fail in Windows system

I have no idea xD doesn't matter now... How do I close the thread?
