From it's website, they said that Open Source Edition (OSE) isn't support USB. I thought, even I'm not sure, mine also OSE version. But today, I really curios is it possible to hack it in order to enable USB support on it?
So, my first aid is Google (of course :p). After around 1 hour searching, I found this link. And I laughed myself. The solution was so easy. You only have to do add yourself into vboxusers group. Here's what I did :
sudo vi /etc/groupEdit it so it will look like this (pungki is my user. It might be different with yours) :
vboxusers:x:121:pungkiReboot your machine, and it's done. Run your VBox, and you'll be found in the bottom right corner, the USB icon appear.
