My official American SNES for Switch controller from My Nintendo wasn't detected until I realized that reWASD was making it be detected as another controller. Quitting out of reWASD didn't help, instead I had to to select the power button in the lower-left corner of that program and turn off reWASD magic.
I don't think anybody needs to bother doing anything about this issue, but keeping it open for awareness.
