Duplicate HID Input

Post by VBtestuser »

Good Morning Forum,

so I have a few questions about how VB captures the user input from an USB HID device (keyboard, mouse, etc):
I guess after you click in the GUI that you want to capture the interactions with the device (e.g. the USB keyboard) within the guest system, Virtualbox is getting an exclusive lock on the event device for this specific USB HID device (let it be /dev/input/event16 for now)?
Although my first question aims to improve my understandings of VB internals, my actual question is the following:
Is it possible to duplicate the input of a user? Considering two USB HID devices (a mouse and a keyboard) are connected to the host system, but everything the user types and also every movement the user makes with his/her mouse is not just happening in the guest but also happening withing the VM.

Thanks in advance.

Best,
