This is both for a device as general and an open connection.
LibUSB abstracts on Mac, Windows and Linux for using USB devices. SO far it's the best generic USB interface we have.
You need libUSB dylib (mac), dll (Windows) and so (Linux) files from LibUSB. For Linux the LibUSB library is usually preinstalled with a LibUSB package, so the plugin finds it automatically.

The HasCapability() API is available.
The library can access HID devices without requiring user intervention.
Note that before being able to actually access an HID device, you may still have to call additional libusb functions such as
Hotplug support is available on this platform.
The library supports detaching of the default USB driver, using DetachKernelDriver, if one is set by the OS kernel.
