Yes. I have tried a bunch of patches around and none works, not even with Ubuntu 14.02 running Kernel 3.18 (see here for a good How To and an explanation of one of the issues - did not work for me).
Definitely not supported in Raspberry as well:
"Problem USB to Serial Adapters
HL-340
CH340 Chipset - Currently not supported by RPi but there is a patch of kernel code here, but it is for a 2.X kernel. If you find you have bought one of these, then it may work under Windows, but as of writing there is no support for RPi. Otherwise you can have a go at getting the patch to work."
It does work with Cumulus, running on Mono. So it may have something to do with the way PySerial communicates with the driver as well.
So, it would seem Linux users would be better off by picking a Nano with an original FTDI chip.
Question: If I am to replace the CH340 Nano with an FTDI Nano will it work without modification (I mean with a C3 instead of an R3)?
