Trouble:
We have observed this problem at may places that you need some data on your pen drive but the USB drive or pen drive does not work. Windows gives a notification
“Found new hardware, USB Mass Storage Device, please install drivers for it.”
Windows will now show a New Hardware Wizard to install the drivers. Lets see in details how we can fix this problem.
Fix:
There are more than one ways in which the USB drives are disabled by Administrators at offices or colleges or schools. These methods are:
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.
We will see how to fix all these situations one by one. But before you begin, you must have administrator rights on that computer to fix the issue. If you don’t have the rights, see this post on getting admin rights on windows computer.
Lets go one by one for the solution now.
Unlock USB ports from device manager:
i) Go to Start > Run, in run prompt type “devmgmt.msc” and press enter. This will open device manager.
ii) Go to Universal Serial bus Controller. See if there are any red colored cross? If yes, right click and enable those USB Ports.
Now try and use the pen drive. If it works fine, then great, else read the next two steps also.
Correct Registry Value for USB Mass Storage device
i) Go to Start > Run , type “regedit” and press enter, this will open registry editor.
ii) Navigate to the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR
iii) 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 steps below to solve the issue.
Install 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. If not, you can download the USB Mass Storage drivers here. Download and uznip the driver files on your desktop.
i) In hardware update wizard, Select the option to install the driver from a specific location and click next.
ii) 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.

hi redankaiah.
First open The Device manager,then
click the “universal serial bus controllers”
then find out which port you need to use in your college system.
then “right click in a “USB ROOT HUB” now you get a properties option. click the “properties option”
Now you get a “USB ROOT HUB PROPERTIES” windows .
Now you clik a “General Tab” in a “USB ROOT HUB PROPERTIES” windows .In the Bottom of this window you will get a “Device Usage” option.Here you can set the “ENABLE ” option.
I think my post is useful to you

Hi,
Firstly I thank your valuable info.

Thank you in advance.

hi nice information
For those who want to enable pen drive through Symantec…..
Go to Registry Editor
HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Symantec Endpoint Protection\SMC
Change the values to “0”(Zero) for
1) smc_engine_status
2) smc_exit_test
Go to Start -> run and type smc -stop
If still not working then check the settings from the Device Manager and enable the pen drive
you are good to go.

how to enable pendrive access blocked by kaspersky end security in my college……..?
Dear sir,
I am viren and my office uses the LAN system which is secured by Cyberoam client. All the computers are installed with xp service pack 2.
Recently they have disabled all the usb jacks for limit the use of pendrives. But the usb are functional for other devices like mouse etc.
When i insert the pendrive it is installed correctly and F:\ removable disk is showen in the my computer. but when i try to access it, a windows opens stating ” access is denied”.. I used the following trics to solve the problem but without sucess:-
1. in device manager the usb storage was already enabled
2. the registery value at (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR)–> start was already 3
3. I installed the usb drivers
4. i tried accessing it by typing the f:\ at he start–>run but same message “access is denied”
5. i tried creating the registery tweak for right protect removal but it was not also useful
I know that pendrive were functional until recently but they are disabled by the IT department due to some problem of misuse of system resources. The IT people have reopen some compute’s pendrive once the executive obtain a special permission from the CEO.
I donot want to mess with the CEO can you help.
In my networked PC, USB pen drives are not opening, as it a appears that blocked by administrator through Symatic end point protection. Pl help to enable the USB port.
