It all depends on what aircraft you fly. The CRJ, WT CJ4, PMDG 737 and SWS Kodaik all use custom events that the Logitech driver will not find
It’s also worth noting that SPAD or Axis and Ohs or similar allows you to get much more out of your devices than the basics. I use the radio panel to set my barons, to set minimums, to control all my G1000 buttons and dials etc. And for me, that’s priceless.
But this is not helping the OP with their problem. I would go look at the PC-6 but my motherboard died yesterday. RIP
