I am building a MCP2200 breakout circuit getting reference from the guide by Microchip itself MCP2200 Breakout Board and I tried with two MCP2200 ICs but it doesn't get detected by the PC. I salvaged a 12MHz Oscillator from an old Arduino Mega board using CH340G IC which didn't work for some reason.

I checked out this post MCP2200 doesn't work everytime and tried to increase the capacitor values across the oscillator pins but still no luck. So my assumption is the oscillator is not working.

Could it really be? As a crystal oscillator is a simple circuit as follows;

I tried measuring the voltage values across osc pins and they were 0.17 V.
