my personal take on this was i was trying to configure the thrust levers in phoenix sim to get to work properly but had no luck and then after i quit fs2020 my pc didnt even recognise the devide and couldnt even update it in the firmware.
the solution on my part was to have flight sim open in the a320 and connect and disconnect the quadrant until it recognises it and then while having the sim open I opened the thrustmaster app and did the firmware update.
hope it helps
