Hello everyone

I am not able to connect to mission planner. Was able to do it before with no problem. But suddenly it broke. RX and TX led's are not flashing. But the green red an blue one's are. Maybe a broken USB to SERIAL chip?

Greetings Sieuwe

Either broken usb , or the driver is currupted redownload your driver and reinstall it , it may work probably. If usb broken, resolder it or use the ftdi connect method.
