Together with the Saitek Yoke there is a throttle quadrant with a “PS2” connection to the yoke’s USB. Another type of this throttle quadrant listens to the article number PZ45 and is connected with an USB plug. Both work identical.
Power Supply: in most situations the power to the usb connected hardware is insufficient; just by a PZ44EX Power Adapter – Saitek Pro Flight Yoke System HERE. In sufficient power results in unpredictable disconnection of attached usb hardware which are connected to the yoke.
