usb_serial_jtag example freezes when pressing a key

While embassy_usb_serial_jtag works - usb_serial_jtag doesn't work for me. Tested on ESP32-S3, ESP32-C3, ESP32-C6 ... all the same.

I tried to run the usb_serial_jtag and embassy_usb_serial_jtag examples and both are working for me. I will try to run them on Windows later today as well

On Windows using espflash (3.1.0) this is 100% reproducible. However using putty it doesn't freeze for me.

Still the embassy example works so there is something strange here

I've tried to run it on Windows, but it doesn't recognize any USB-SERIAL-JTAG port ... I followed steps from IDF and it still doesn't work.

This is most probably more of a problem in espflash than with HAL code. While the problem is seen when flashing and monitoring the problem isn't present when just flashing and the running espflash monitor separately

Recreating the serialport instance before monitoring might help - in any case this is definitely not a HAL issue but an espflash issue
