Copies control data into the control data buffer This constructor is used when requestType has the UsbCtrlFlags.Direction_In flag and this request will contain control data (more than just the setup packet). Allocates MonoUsbControlSetup.SETUP_PACKET_SIZE + data.Length for the setup packet. The setup packet is stored first then the control data. The data array is copied into the setup packet starting at MonoUsbControlSetup.SETUP_PACKET_SIZE. This contructor is similar to libusb_fill_control_setup().
MonoUsbControlSetupHandle ( byte requestType, byte request, short value, short index, short length ) : System	Allocates memory and sets up a control setup packet. This constructor is used when: requestType has the UsbCtrlFlags.Direction_In flag and this request will not contain extra data (just the setup packet). requestType does not have the UsbCtrlFlags.Direction_In flag. This contructor is similar to libusb_fill_control_setup(). Allocates MonoUsbControlSetup.SETUP_PACKET_SIZE + length for the setup packet. The setup packet is stored first then the control data.
