How are you starting your VM? Are you > specifying the USB device in the USB Device Filters section of the GUI, or > from the Devices Tab of the VM? Hi, I start VirtualBox from the GUI "Virtual Box". Before I was starting it from the Device Tab. But now now devices are listed anymore.... :-( Also, when I try to use the USB Device Filter section of the GUI, it only tells mie: "No Devices available".... :-( Maybe I have to install the machine from scratch...
