I have been using (1) MCP23017 connected to a Raspberry Pi 3 for some time now with no issues. But I noticed yesterday some of my input widgets disappeared. After some troubleshooting I noticed the MCP expansion chip does not display on windows 10 at all (under extensions) but does display on the IOS app. I didn’t know if this problem had anything to do with the recent update? I could have a hardware issue but the problem seems suspect to the update.
I am also using a Piface 2 (set up as a MCP23S17) on a different Pi 2 B and it seems to be working fine on both the IOS and Windows 10.
Any help or info would be greatly appreciated.
