Some progress with getting a USB device recognised.
As a work around I copied the working Blink project and edited the main.c and CMakeLists.txt to reflect the Hello World USB example.
( As noted above Cmake was failing to find nmake in some instances. I am not clear where the directive for finding nmake should be or if that is needed.) - hence the workaround by cloning.
Working 'Hello World' on PICO W
CMakeLists.txtmain.cThe USB device enumerates correctly in Windows and appears as a COM port however there is also an 'Other Device' this one is called 'Reset' and has the relevant HID and PID !!
Small steps but no I2C Scanner as yet.
