Hi,

We are having 40+ Systems in Laptop's & Desktop's. In this we are having Ubuntu 12.04 to 17.04 (all the versions)

So we want to know how to block the USB Port for non usage of Pen Drive, Mobile, Hard Disk etc

Thanks in advance.

If you Google for Ubuntu block usb, you will find many useful results, including (the first three):

Let us know what works for you.

Thanks.

How about link below, have you tried it already?

Thanks for your response.

I have not tried this because in this USB Keyboard & Mouse will also get disable.

You could use polkit to restrict mounting of removable media only (ie superuser password prompt). Presumably your users won't/shouldn't have administration access to the respective machines, so this will limit the ability to mount removable media. As you want to support a range of *buntu versions, some will likely still be using the udisks framework, while more current versions use udisks2 ie two different rules required. The polkit framework has changed a bit over time, so I'll leave to research this for yourself, but here are some references and example threads that may be of value to you

The opposite question, but still shows the general process...

Then I guess you can create or develop your own software to specifically disable and enable specific USB port.

I think the best way to do it is to implement a policy, not to use USB devices. Whoever violates, no excuses and no question ask will be sacked on the spot. Those who will not agree to the policy a resignation should be presented in the next hour after the implementation of the policy.
