TTGO T-watch, CP2104 and Mac

Hi, I hope this is the right forum part. I think my problem is a driver problem, so I hope it is.

TL DR first: The ESP32-based watch wont connect to my mac running Mojave, even though I have the drivers (CP210x) installed and the board profile downloaded and selected.

And background: I bought this neat and cheap watch-shaped development board for my kids, the TTGO T-Watch. It's ESP32-based, features a touch display, an RTC and a bunch of other sweet stuff. Most of the specs are there in the Banggood listing:

Lilygo TTGO T-Watch

Also, here's the projects GitHub:

Library etc T-Watch

Most of the documentation is focused on learning the users to download and install Arduino. I've used Arduino for some time, so I haven't had any problem downloading and running the board profiles in the Board Manager. I also downloaded and installed the latest CP210x driver for Mac. But the watch doesn't show up on the ports when I try to connect. I have a Macbook Pro 2015 running Mojave.

So far:

  1. Tried doing the same thing on a Virtual PC running Windows 10 on my mac, but no difference.
  2. Uninstalled and reinstalled the driver, tried installing legacy drivers as per this Medium article: I Fixed My UART-USB Problem And So Can You .

But nothing works. Sadly, I don't have any other ESP32 board to try with, but I have tried different Arduino boards and they all work. Also tried an ESP8266 board, which worked.

Anyone? My 10-year-old was really psyched about trying this one out with PictoBlox, and he's very disapointed now. So any help fixing his birthday present would be very appreciated!

Warm Regards

Does the watch work? Do you see anything on the display?

Using such cheap equipment I would assume you have received a faulty device.

You might try to search for USB devices. I have no clue how that works on a Mac, on Linux the first tool for inspection is lsusb.
