Hello,
Did you try to use config-pin on your terminal while plugged in? You may need to adjust your “already-default” configured pins.

P.S. So, if I wanted to set up PWM on “P9_14,” I would type, sudo config-pin P9.14 pwm. I would then hit the enter/return button afterwards. To check to see what pins are configured and how they are configured, use the -q argument. So, to check for “P9_14,” you would type sudo config-pin -q P9.14 and then hit enter/return.
