Serial2xsbug Connection Error

[tesanders]

I've been able to compile, build, flash, and run the "MODDABLE/examples/helloworld" app on a "xiao_esp32s3_sense" module. When I attempt to run a simple MCU Edition flow (inject>debug) on the same module, the app is successfully built and flashed onto the module, but the following error message is generated and the app never starts:
>~/Projects/moddable/tools/serial2xsbug/serial2xsbug_lin.c:116 Connection refused

Welcome, @tesanders.

There were some issues connecting to ESP32 devices with a built-in USB port, like the ESP32-S3, on macOS and Linux. Working with @mshioji, we were able to find a solution. The fixes will be included in Moddable SDK 5.7.0 which should be released in the coming days.

Thank you for the follow-up! I'm looking forward to the SDK 5.7.0 release
