How can I restrict a VirtualBox guest from accessing certain USB ports/devices on my host machine? I have some theories on how I might do this, but I really can only guess.
For further clarification, let's say a USB device was causing issues on my guest machine in VirtualBox, but that USB device is critical to my host machine. I need to blacklist VirtualBox from using certain USB devices.
The host being Ubuntu and the guest being Windows.
Update: I disabled the USB controller, uninstalled the extension pack, and even set mouse and keyboard to PS/2. Guest is still able to access my USB ports even though I have done no configuration to allow it to do so.
