For my project I designed a little board for the g80. I tried to consider your suggestions from https://www.ghielectronics.com/community/forum/topic?id=24160, thus placing crystal and caps as near to the ic as possible, not using autorouter, etc. Nevertheless, when I plug in the board, it does not get recognized by windows. I checked for shortcuts or wrong connections, but everythong seems to be ok. My question: could you please just make a quick check on my desing to lead me into the right direction?
