Hello everyone!
I am currently trying to create a custom PAB carrier board for a Holybro pixhawk 6x and I am running into problems with USB communication. I have bought and examined the Holybro carrier and it seems usb D+ and D- go straight though an ESD protection circuit into the autopilot module. I have tried this and I am not managing to get a com port connection even through I have verified the autopilot is booted and working normally using a CAN sniffer. Any help on this issue would be very welcome.
