my friend is having the same exact issue after buying this https://www.amazon.com/Gamecube-Controller-Adapter-Black-Switch/dp/B07D6HXJ2Y/ref=sr_1_2_sspa?crid=38Q1UMJ8ZQDA7&keywords=gamecube+pc+adapter&qid=1553223692&s=gateway&sprefix=gamecube+pc%2Caps%2C144&sr=8-2-spons&psc=1/ i think the generic adapters might not work/have a different set up process,id recommend getting the mayflash adapter or an official Nintendo one
