ESP32 Dev Board - No Serial

Development Boards ESP32

I recently purchased an ESP32 Dev board - https://www.sparkfun.com/products/19177 - and it will not enumerate. I’ve tried Linux and Windows 10.

on Linux I see this - ==> /var/log/messages <==

For a CH341 the vendor and product are wrong.

I have an Artemis board also with a CH341 chip, and it works fine.

Thought it might be a Linux Ubuntu/Mint problem, but Windows is the same. Even tried a Macbook and nothing.

Any thoughts on what to try next?

for reference the artemis board looks like this when plugged in:

Try reinstalling the drivers http://www.wch-ic.com/downloads/CH341SER_ZIP.html and see how that goes - if it is still unresponsive (and other CH34x devices work) then it is likely a defective board. Contact the seller with the info (if purchased from sparkfun go to www.sparkfun.com/returns/ , if purchased elsewhere contact them for similar)

Been there done that - and Sparkfun has sent a replacement board - both work exactly the same. I’m thinking they loaded the wrong firmware, or something like that.

CH342SER_Zip - doesn’t recognise the USB device, I’m thinking because it has the wrong Vendor and Product ID. Why should it ?

and I’ll add just tried it with a Raspberry Pi 4 - exactly the same result - followed the “installing CH34X driver” exactly for the Pi - no difference - has anyone managed to get one of these to work from the latest batch?
