I can't mount в USB device in в Виртуальный windows machine, despite trying the общепринятый solutions

гve looked through post upon post about possible solutions and гve tried them all (check VM settings / filters, download guest additions, installing Vbox расширение pack, making sure my username is part of the group 'vboxusers', downloading the most recent версия of VirtualBox NOT in Программное обеспечение Centre, making sure device is unmounted in host ВЫ) and still had не luck. My Webcam for whatever reason is fully integrated but whenever I go to 'USB devices' therВs nothing listed so it won't let верьте any в USB filters. Any suggestions would be appreciated. P.S. гm using ubuntu 15.10 and VirtualBox 5.0.10 and my guest ВЫ is Windows 8.1 64 - бит (not that I think it matters).
