I've installed virtualbox from http://download.virtualbox.org/virtualbox/debian on my debian unstable. I'm trying to connect a usb device to that machine (a usb camera at the moment). It appears under devices->usb devices->camera 0100 but it is grayed out and I can't mark it. I tried adding write permissions to /proc/bus/usb, /dev/bus/usb and /dev/*usb* but it doesn't seem to help. Any idea on how to make usb work? Thanks
