        bDeviceSubClass - Device subclass code.
        bDeviceProtocol - Device protocol code.
        bMaxPacketSize0 - Maximum packet size of endpoint 0 (in bytes).
        idVendor - Vendor ID.
        idProduct - Product ID.
        bcdDevice - Device release number in BCD format.
        iManufacturer - Index of the manufacturer string descriptor.
        iProduct - Index of the product string descriptor.
