Did dome more testing on a different ESP2866 board (NodeMCU Lolin V3 Module ESP8266). With this WCH CH340G chip and Linus standard kernel driver the communication works fine.
With different ESP2866 board(AZDelivery D1 R2 ESP8266 12-F) Mac works out of the box and Linux only with driver mentioned above. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1915661 Title: WDH - CH340G USB UART not supported by ch341 driver in all chip revisions Status in linux package in Ubuntu: Confirmed Bug description: Hi, the USB UART chip CHG340G is used by many developer ESP2866 boards to connect to USB serial. The standard kernel driver des support a lot of those CH340x chipset but it does currently not support the WDH CH340g with standard ch341 driver. Nevertheless there exists a working driver from the vendor since yaers. http://www.wch.cn/downloads/CH341PAR_LINUX_ZIP.html https://sparks.gogo.co.nz/assets/_site_/downloads/CH340_LINUX.zip https://sparks.gogo.co.nz/ch340.html Is it possable to get the mainlaine driver updated to support CHG340G out of the box without patching recompiling custom kernel. There are milions of CH340g chips on those ESP2866 boards out there.
