--- Comment #3 from Tomasz "CeDeROM" CEDRO <tomek@cedro.info> ---
There is a discussion on AVRDUDE GH project regarding CH340 chip problems.
These problems are not found on OpenBSD and NetBSD:

https://github.com/avrdudes/avrdude/discussions/1639#discussioncomment-8252976

I also searched for boards that I have and found out that aside non-detectable
ESP32-S3-Pico devkit I also have WaveShare 21442 USB-to-UART converter with
CH343G and it seems to work! It does not work as well as CP2101 or FTDI chips
for ESP32 flashing (control lines) but for terminal it seems to work :-)

I have ordered 2 x CH340 + 1 x CH341 boards they should arrive next friday will
check with those.
