Windows 7: can't install usb drivers

24 Jul 2012   #11

Window 7 Professional
USB Driver problem

Hi Loops ,

You have not mentioned where is that 140 GB data lying . Normally everybody keeps the data in a separate partition (D: partition ) If that is so , you will not loose any thing by loading the OS afresh. You can reformate the C: partition and load the OS.

USB Driver problem

Hi, Loop,
inform , if your 140 GB Data is in D: partition or not. If so what is the hesitation in reloading the OS afresh, that will cause no data loss

Hi, Loop ,
This is my 3r reply. If your HDD is not partitioned in to C: & D: drive , you can do it by shrinking C: , releasing some space & make it as D: partition. Copy all your data to D:. Then go on with the task of loading the OS afresh.
If you do not know how to shrink C: partition let me know

Windows 7 Ultimate x64

I'm writing this post as the problem affects later Windows releases.

I don't exactly know which cache architecture lies behind these drivers, but I assume that they can be regenerated by installing a non-similar, but compatible driver instead of the one that cannot install.

My solution was to forcefully install a generic USB driver (shown in the compatible drivers' list) instead the one offered by default and/or manufactured by Intel. When the installation was successful, I immediately reverted to the driver manufactured by Intel. (The chipset package driver did not fail this time.)

With Regards to your issue you can try the steps mentioned below.

1. Boot the system to safe mode & check if the usb ports are working.

3. Even after all these steps if you are facing the same issue then try this last option.

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 (donít touch the folders!) and choose properties.
4- go to security tab
5- click Edit

7- Click ok.
8- Repeat to every file
9- Select all the files (*.dat and infcache.1)
10- Press shift+del

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
