Lost USB functionality with 5.0.12 after recovery

[CFS]

I backed up my VM folder to external HD. I then upgraded my OS to Ubuntu trusty 14.04.3 LTS. I re-installed virtualbox 5.0.12 and corresponding extension pack. I now have no usb functionality. Can someone please help. Thanks.

user name in the VBoxusers group?

Thank you Perry! I can't believe I overlooked this. I used the following commands after closing virtualbox:
sudo usermod -a -G vboxusers <username>
sudo adduser USERNAME vboxusers

I restarted my computer and USB functionality is now restored.
