Extra : When VirtualBox told you to recompile kernel

In my cast, I just installed kernel-module and gcc before recompile done. you can see error in log file.

1. Open Terminal, type sudo gedit /etc/fstab

2. It’s open Gedit to edit fstab file, add this
none /proc/bus/usb usbfs devgid=46,devmode=666 0 0
to the bottom line of the file.

3. Save, goto System > Administration > Users and Groups

4. Click Manage Groups buttons, find ‘vboxusers’, select and click Properties

5. Select your login name by fill the box to add your account to vboxusers’s group

6. Restart System, and enjoy to your virtualization world

* VirtualBox have 2 version, Normal and OpenSource. The VirtualBox which in Ubuntu’s repositories is OpenSource (called VirtualBox OSE) this version is not support USB. However, you can get the Sun xVM VirtualBox which full support for all devices from VirtualBox.org, it had repository for Ubuntu’s users to use ‘apt-get’ and, can update automatically like software on Ubuntu’s repositories.
