wisebear Posted March 1, 2018 Share Posted March 1, 2018 Several requests have already been made on the forum (Link 1 and Link 2) to add support for CH340 USB to TTL converter. I have already sent a request also to Limetech, but haven't received any feedback yet. Enabling the driver that should be present in the kernel, would allow the use of cheap arduino boards for home automation purposes. Quote Link to comment
Reynald Posted December 23, 2018 Share Posted December 23, 2018 (edited) 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Unfortunatly, IDK how to compile unraid kernel and documentation is outdated Edited December 23, 2018 by Reynald Quote Link to comment

Here is a link to the CH340T adapter I am using https://www.amazon.com/gp/product/B00NKAJGZM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 When I plug it in, I get the following in syslog...full diagnostics attached.

goinsnoopin Posted May 18, 2019 Share Posted May 18, 2019 @limetech My issue is resolved. I had the serial adapter plugged into a usb 3 port. When I moved the device to a usb 2.0 port everything started working as expected. Unraid assigned it to /dev/ttyusb0 and all is well. Dan Quote Link to comment
