Hello all,
@limetech
We are several users using Unraid with home automation or other hobbyist using arduinos. Me it will be to use a USB Watchdog, very usefull on an unRaid server when system hangout and you're not at home. I will do a writeup when got it working.
Please, may you include the driver in next kernel compile? Here is the official driver from ch340/ch341 chip manufacturer: http://www.wch.cn/downloads/CH341SER_LINUX_ZIP.html
Also, maybe modules are already available in kernel source also: http://manpages.ubuntu.com/manpages/xenial/man4/uchcom.4freebsd.html
Unfortunatly, IDK how to compile unraid kernel and documentation is outdated
