ESP32s2 /dev/ttyACM0 ver1.20

[ajvperth]

Hello,
I have a problem to communicate in linux with micro python ver 1.20 LOLIN_S2_MINI_20230426-v1.20.bin

on Linux: On ESP32, version 1.20 communication through /dev/ttyUSB0 is OK
on Linux: On ESP32s2, version 1.19 communication through /dev/ttyACM0 is OK
on Windows: On ESP32s2, version 1.20 communication through com3 OK (in Virtualbox with Linux host ttyACM0)
on Linux: On ESP32s2, version 1.20 communication through /dev/ttyACM0 ==> no response

abstract ESP32s2 v1.19 on Linux OK while v1.20 no response
I would appreciate your thoughts about how to get 1.20 working under Linux

my Linux OS is openSUSE Tumbleweed

Thanks

I am a bit further,
I connected micropython version 1.20 on ESP32s2 to ubutu 23.04 and I have the REPL
On openSUSE Tumbleweed I have the REPL with version 1.19 but not with version 1.20
On openSUSE and Ubunto: lsmod --> cdc_acm 49152 0
On openSUSE only: lsmod --> usbcore 16 .........,cdc_acm, ........

I think it is not micropython related but a linux problem
but ..... something changed between 1.19 and 1.20
thanks
