If you have an old USB2 or even USB1 hub (preferably a powered one), try with it.
You must calibrate them, or it won’t work ok.
Device Manager/Devices and Printers/right-click the device/Game Control Settings choose Properties or using DIView.
It will be easier if you calibrate by plugging only one at a time, and without any other controller plugged.
Question: are they both USB, or is one plugged into the yoke ?
Only once they will be OK under Windows, you’ll have to finalize in MSFS.
To bind them for twin engines planes, see here (a bit long, but really step by step):
