The daughter board USB goes straight to the SIMCOM module. The main board USB needs to go through async as the ESP32 chip does not support USB directly. Even the upcoming ESP32-S3 doesn’t seem to support it. Or am I missing something? Regards, Mark.

For future versions of the daughter board (and main) is it worth adding the USB D+- lines and move away from the Uart interface? _______________________________________________ OvmsDev mailing list OvmsDev@lists.openvehicles.com http://lists.openvehicles.com/mailman/listinfo/ovmsdev
