just found command
dtoverlay -l
lists loaded devices, which gives the following
P# dtoverlay -l
Overlays (in load order):
0: fe-pi-audio
1: mcp23017 addr=0x20 gpiopin=12
2: mcp3008 spi0-0-present=true spi0-0-speed=1000000
so why is #2 not showing as used by the i2cdetect scan (0xa = UU (Loaded), but 0x20 is not UU)
