I'm having a little bit of a security issue, and I need to deny all access to my USB ports, so that no one can use the USB ports on my computer, but at the same time, I need to allow ONLY my USB key. I've been fooling around in MMC under: Local Computer Policy/Computer Configuration/AdministrativeTemplates/All Settings: Allow Installation of devices that match any of thse device IDs. Adding my hardware ID from my USB key to this did not accomplish anything. Any other ideas?

Hi, As far as I know, if you want to disable USB ports, you could enable or disable USB port in BIOS, but the problem is you cannot use those USB ports for any purpose like connecting USB keyboards or mouse or any devices. Here, you could set the following policies to check how it works: 1. First, you should go to “Device Manager” to find out your USB key Hardware ID. 2. Enter USB key Hardware ID into the Group Policy Setting Computer Configuration –> Administrative Templates –> System –>Device Installation –> Device Installation Restrictions -> “Allow installation of devices that match any of these device IDs” 3. Within this policy you will want to set it Enable, and then click on the “Show” button to enter your USB key hardware ID. 4. The other related policy is the Group Policy Setting Computer Configuration –> Administrative Templates –> System –>Device Installation –> Device Installation Restrictions -> “Prevent installation of devices not described by other policy settings”, set it Enable.
