ESP32S3 lost USB download features since deep sleep test

[mleforestier]

Hello Support,

I am here because I am facing strange problem with a custom board with an ESP32S3 chip. During developement, I tested some deep sleep capacities with EXT0/EXT1 wakeup from IO0 pin. Since I flashed that firmware, my device is not able to receive firmware through USB bus. I added a USB/Serial device for catch message on TXD0 and when I force device in download mode (BOOT0 at 0), I am able to see message "... (USB/UART0)...wait for download".
If I let the esp-idf programmer use the USB/Serial device, I am able to program the firmware and the firmware runs normally. But USB is not usefull anymore ...
There is some generic message I receive from tools

Chip is ESP32-S3
Features: WiFi, BLE
Crystal is 40MHz
MAC: 68:b6:b3:3c:65:48

I am using esp-idf 4.4.3. I have the same behaviour with flash_download_tool_3.9.3(not able to program using USB but able to use USB/Serial).

Thanks a lot for your help

Regards,

Mickael

PS : I have the same problem with esp32s3 eval kit
