I have a new computer installed with Ubuntu 12.04. Then I want to install wireless driver named compat-wireless-3.5-3. Before that, the driver folder to /home/kevin.

I want to install it on /opt directory. Before install the driver, i want to copy the driver folder from /home/kevin to /opt. I try to use ordinary copy (Right Click Copy Paste), but the paste is blured.
After that, i tried using this on terminal:

sudo cp /home/kevin/compat-wireless-3.5-3 /opt

But i get this command:

cp: omitting directory `home/kevin/compat-wireless-3.5-3'

What does the command mean? I can't copy the driver until now.
