Allow only one USB for XP

I think you will need to use a software solution rather than hardware if you want to essentially disable USB pen recognition for all but one drive.

Give this a look:  http://www.usbcopynotify.com/

We use Sanctuary from Lumension to do this.

Hello ,

 If you want to disable all USB ports there is easy way to do it. But you mentioned to use only one USB port. I recommend you to use special software which allow I/O's or ports. There was software called SecureNT . If you can find it then it will solve your request. Otherwise you can  check this software:

Dear Nizam,

Not one usb port i want to allow only one usb stick which should be used for data transfer and rest of pen drives should remain disabled.

looking for some open source freeware

there's a product called "DeviceLock" that will definately achieve what you want, but you could also do it by using Windows 7 Ultimate or Enterprise and enabling BitLocker..

you can set Win7 to only mount encrypted drives, so if you restrict admin access to the other users and deny the creation of bitlocker volumes by policy, you can get most of the way there..

DeviceLock controls which users can access what devices .
I believe he wants only one USB stick to function and none other.
