Saitek Throttle used in the cessna yoke combo

Hi

Looking for a bit of advise on how I can still use my throttle quadrant from my Saitek cessna yoke as it does not have a USB  connection.

I have recently bought the X55 and use that pretty much all the time now,but I still prefer my throttle quadrant for some of the features that I can use it for eg speedbrakes and reverse thrust.

Is there on the market some sort of converter plug that can change the connection on the throttle to a usb so I can plug that into my pc

cheers
