Set up USB for Virtualbox
I have Ubuntu 12.04 as host and Win7 as guest. I installed VirtualBox 4.1 and Extension Pack 4.1 from Oracle website. I also enabled USB 2.0 from Settings of my VM. My Win7 VM doesn't regconize USB (Flash Drive and Kindle Fire). How to fix it?
Update: I added my current user to vbusers group but it doesn't work as well.
