Ok, I'm still progressing on more of that init code, but what I've got pushed to https://github.com/karlp/linux/tree/ch341-3.18.6 at the moment is _substantially_ more reliable than the original code. It might already fix your problems. With the original code, many software packages I tried wouldn't actually work unless something else had setup the tty explicitly ahead of time. I'm still continuing to add the parity and stopbit configurations, and then need to review break/clear and hardware flow control. Cheers
