Virtualbox not seeing any usb devices in the usb filters settings
Solution 1:
This may help you access the USB devices in your guest OS hosted in Ubuntu
First install dkms :
sudo apt-get install dkms
Next install Gnome-System-Tools
sudo apt-get install gnome-system-tools
Now launch the application - Users and Groups. If you're using unity you can do this by tapping the Super key and type user then click Users and Groups icon to start up the User Settings.
Click Manage Groups, find vboxusers, click properties, add your own user name and any other desired users to the vboxusers group. Click Ok.
Next you'll have to log out (sudo restart lightdm if you're using this DM) and back in. Now start VirtualBox and proceed with adding the USB devices.
Solution 2:
This command will add your account to the vbox users group. It will allow your VirtualBox to detect USB flash drives.
sudo usermod -G vboxusers -a $USER
$USER value is your username. You can see it with echo $USER
$ whoami
foo
$ echo $USER
foo
You could also replace $USER by your Home username.
Then logout or reboot your computer and VirtualBox will now detect USB devices.

Solution 3:
It should be enough to run
sudo gedit /etc/group
then find vboxusers line and add to it's end Yours user name.
After this reboot is suggested, but logging out or kill -9 -1 and logging in should be enough.
Solution 4:
After having added yourself to the vboxusers group:
sudo gpasswd -a $USER vboxusers
If you naturally do not want to log out or restart for whatever reasons there are, you may run VirtualBox with a forced effective group:
sg vboxusers virtualbox
This should be unnecessarily after the next reboot.
Solution 5:
I had the same problem with Linux Mint 17 (Ubuntu 14.04) using the standard distro version 4.3.20. gnome-system-tools and dkms were already installed but open-vm-dkms wasn't. I did this:
sudo apt-get install open-vm-dkms
After a re-boot, I could see the USB devices. The package exists in Ubuntu 12.04 and 14.04 as well so I assume it would work there too.
Could be a dependancy problem?
