USB describes four types of transfer: Control Transfer, Interrupt Transfer, Isochronous Transfer, and Bulk Transfer. Each of these transfers is dedicated for different device requirements, and their explanations can be found in [2]. Our device is using Control transfer. This transfer mode is dedicated for device settings, but can also be used for general purposes. Implementation of Control transfer must exist on every USB device, as this mode is used for configuration
