Linux Mint 13 on VirtualBox needs some tweaks to use USB mouse

Since I’m kind of disappointed with the lasted Ubuntu version (12.04), that just makes my 4 year-old laptop useless, I’m now considering alternatives.
The first one that popped up was Linux Mint.

I’ve tested the latest build Linux Mint 13 on VirtualBox and I’ve noticed that my USB mouse didn’t work there.
To fix this I had to execute this command:
sudo usermod -aG lp <MY_USERNAME>

and it fixed that issue.

I’m going to try it a bit, just to see if I’m ready to do the switch.
