What's the state of the device, as reported by "VBoxManage list usbhost"?

It's unlikely, but of course still possible that the changes have this 
weird side effect...

On my system (with a filter for the USB device) there's a quirk with 
logically detaching a USB device the first time, too, but I already 
verified it's definitely unrelated to the changes - it immediately 
re-grabs the device as for some reason linux assigns a new device name 
to it...
