Unlock pen drive at office or college PC if it is blocked or disabled

   Ever got angry on your college or office because you can't use Pendrive and keep  getting install the driver ,etc 

             The USB port can be disabled by 3 methods ,
1. By Disabling USB Ports from Device Manager.
2. By Tweaking Registry values for USB Mass Storage Devices.
3. By Un-installing the USB Mass Storage Drivers.

Don't worry in this post I will show you how to solve this problem , to perfom this method  you should have Administrator Rights .  To get the administrative rights read the below post :


I assume you have administrator rights. Now let’s see how to fix all these situations one by one.

1) Unlocking USB ports from device manager.

#1 Go to Start > Run, in run prompt type “devmgmt.msc” and press enter. This will open device manager.
#2 Go to Universal Serial bus Controller.
#3 See if there are any red colored cross? If yes, right click and enable those USB Ports. Enable USB at Device manager

Now try and use the pen drive. If it works fine, then great, else read the next two cracks.

2) Correcting Registry Value for USB Mass Storage device.
#1 Go to Start > Run , type “regedit” and press enter, this will open registry editor.
#2 Navigate to the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR
#3 Double-click on the “Start” key to modify its value, change the value to 3 and press OK.

Now remove and connect the pen drive again, it should work fine, if it does not, then it means the drivers are missing. Follow the 3rd crack below to solve the issue.

3) Installing USB Mass Storage Device drivers

In case the USB Mass Storage drivers are not installed, windows will prompt you to install the driver. In such a case, windows will launch Hardware Update Wizard. If you have USB Mass storage drivers, you can install it and restart the computer, it should work.

#1 In hardware update wizard, Select the option to install the driver from a specific location and click next.
#2 Now on this screen, click browse and select the path on which you have un-zipped the drivers and press ok.

NOTE: Windows may give you a warning that the drivers has not passed Windows logo testing, so stop installation or Continue anyway, Select Continue anyway to complete installation. Now restart your computer and re-insert your pen drive, it should now work.
