USB Port Read Only

[unclenelli]

Does anybody know if it is possible to make a USB port read-only?

I need to stop any data being written to any USB flash memory, but still need to be able to read from a flash memory.

Any ideas????

In hardware I don't know, but for Windows (SP2 and above) just change a registry key.

Start the registry editor (regedit.exe).

1. Navigate to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageD evicePolicies subkey. (Create the StorageDevicePolicies subkey if it doesn't already exist.)
2. From the Edit menu, select New, DWORD Value.
3. Type the name WriteProtect and press Enter.
4. Double-click the new value and set it to 1. Click OK.
5. Close the registry editor.
6. Restart the computer.

Or you can use Thumbscrew - Thumbscrew: Software USB Write Blocker - to do it for you.

Obviously, anyone who knows the trick can reverse it, but for casual snoopers this may be enough. Hardly secure in the real sense though.

As Mac says.

If you are really serious about blocking writes, then you need a physical bridge device as relying on some software solution alone won't cut it. Example of a bridge device :
