ESP32-S2-DevKit-Lipo-USB USB to Serial

[findmyname]

It seems that this feature isn't supported in Ardunio so far. There is also this issue referenced about by @luboOlimex but it is still open.

I think the S2 branch was recently merged to main branch, and you no longer have to deal with specific S2 branch in Arduino. Double check if that is the case. Try if you see the S2 support using the default branch.

I have serial over USB & web usb working fine with this board and the latest https://github.com/espressif/arduino-esp32#2.0.0-alpha1 release.

Does not work as well as the native serial interface and flashing only works 50% of the time without going into bootloader mode & can't monitor directly after reset, but it's fine for a start and you can still get the job done. Hoping at least the flashing issues resolve themselves over time
