CH340G Working

Nice to see CH340G finally registering correct on Windows. The circuit below works just fine.

The first you always should do is to measure if you have power – in this case 3.3V – I actually did, but as I finally measured on the pins I noticed that I actually did not. Looking at my schematics (and routing) I realized that I had connected the circuit to the wrong 3.3V that I had not assembled yet – doh…

It is an annoying error and even more annoying that I did not see it straight up. The real problem here is that I have made it difficult for myself not providing test points on a rather complex board . But, I am very happy to see this working as expected.
