I'm running VirtualBox
Version 4.2.0 r80737.
I have a USB keyboard that I usually just want filtered to the VirtualBox, but occasionally I want to free it up so that I can use it in the host OS as well. I was looking at VBoxManage in the documentation, and saw the promising looking "usbfilter" option, but when I tried
usbfilter add/modify I got the error:
The machine 'your name here' is already locked for a session (or being unlocked)
So it seems that it doesn't affect the running machine (at least not through that option). I really just want to be able to programatically do the same thing as going through the menu to Devices > USB Devices > USB Keyboard .
I don't care whether it's from the host or guest OS that I can access it.
Is this possible, and if so, how can I do it?
