Where to place a global class in MVVM?

Question

C++ / C#

I have a class in Model for working with USB HID, but there is only one USB device and an instance of the class is created only once and then connected to the device
Where should I put it if I have several windows? I cannot initialize this class in each ViewModel
i.e. I need one global property and catch updates from it in all windows? If so, where should I create this property and how to bind to windows?
