8.2. USB-HID and USB-VCP Interface Specifications
There are two models that use a USB interface: HID (Human Interface Device Class) and
COM (Communication Device Class). The USB-COM model is referred to as USB-VCP
because a VCP (Virtual Communication Port) allows virtual serial communication and the
commands can be transmitted from the host computer.
