Description

I am unable to communicate with the device via the usb-serial interface. Except for flashing.
During flashing the "1200 pbs reset" does not work. I need to reset the device and do the usual ESP32 thing.
Tried using the web client with serial on two machines. Windows and Linux. Both find the correct USB port but the screen just hangs.
Also tried using the mechtastic python app. "meshtastic --port /dev/ttyACM0 --info". THe app just hangs.
I can see that "/dev/ttyACM0" shows up when I connect the device.
I also tried using the iphone app to set the serial to 115200 baud and "NEMA Positions". No output from the device.

Relevant log output
