There are two USB-related issues in VBox 4.0.6 (Linux hosts only). It is now mandatory to be member of the vboxusers group to access USB devices. And there is a bug in the startup script (/etc/init.d/vboxdrv). That script creates /dev/vboxusb if that directory does not exist yet. Unfortunately it uses wrong permissions: 640 is incorrect for the directory, 750 is correct. Search for 640 and replace it by 750. Then remove that directory and do sudo /etc/init.d/vboxdrv start VirtualBox should now be able to access the USB devices again. Kind regards, Frank -- ORACLE Deutschland B.V. & Co. KG Dr.-Ing.
