Issues with ESP_CONSOLE_USB_SERIAL_JTAG if set light_sleep_enable = true (IDFGH-7295)

[AxelLin]

Environment

• Module or chip used: ESP32-C3-DevKitM-1
• IDF version: v5.0-dev-2586-ga82e6e63d9
• Build System: idf.py
• Compiler version: xtensa-esp32-elf-gcc (crosstool-NG esp-2021r2-patch3) 8.4.0
• Operating System: Linux
• Power Supply: USB

Problem Description

I have below config setting:
CONFIG_ESP_CONSOLE_USB_SERIAL_JTAG=y
CONFIG_RTC_CLOCK_BBPLL_POWER_ON_WITH_USB=y

And
esp_pm_config_esp32c3_t pm_confg has .light_sleep_enable = true

In my by test running "idf.py -p /dev/ttyACM0 monitor", I usually got below messages after running for a few minutes:

device reports readiness to read but returned no data (device disconnected or multiple access on port?)
Waiting for the device to reconnect....

ps. The module still working (it can still upload data to my server), but I cannot see any debug messages.

The dmesg shows bellow errors:

Re-run "idf.py -p /dev/ttyACM0 monitor" does not work, it shows below error:

Executing action: app-flash
Serial port /dev/ttyACM0
Connecting...
/dev/ttyACM0 failed to connect: [Errno 32] Broken pipe
No serial ports found. Connect a device, or use '-p PORT' option to set a specific port.

I have to press the reset button on the module, then "idf.py -p /dev/ttyACM0 monitor" works.

Expected Behavior

According to the doc: https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/api-guides/usb-serial-jtag-console.html
If the application enters light-sleep (including automatic light-sleep) or software reset, etc. The USB CDC device will still work on the system.

Actual Behavior

Hit below issue and idf.py stop working:
device reports readiness to read but returned no data (device disconnected or multiple access on port?)
Waiting for the device to reconnect....

This seems to be the same issue as #8507, i would suggest to close this one and use the older issue to keep track of this.

I think it's the same issue as #8507.
I do hope someone is working on the issue because it seems there is no response on #8507 so far.

@AxelLin I'm sorry, noone is working on that, yet. The colleagues who are familiar with the "light sleep + usb_serial_jtag" feature currently don't have access to the hardware required, due to the situation in Shanghai. We'll pick up this task as soon as this is resolved.
