And it finally works, after much head-scrstching,.many (many!) dry joints, a few broken wires and having to switch GPIOs because #tinyusb seemed to want to hold on to gpio1+2 despite my best efforts, my #MGT #SamCoupe USB-HID mouse adaptor prototype (based loosely on the #RP2040Mouse project) is working
Forgot to add, my fork of the #RP2040Mouse project for the #SamCoupe is up on GitHub at https://github.com/gwinkless/RP2040_Mouse_SamCoupe
