Error occurred when using JTAG to burn the program to ESP32:libusb_handle_events() failed with LIBUSB_ERROR_IO

[Sirius]

Hi Team

The JTAG debugger I used was espressif's official ESP-PROG, the compilation software was VSCODE, and the connection confirmation was in accordance with TMS-TMS,TDI-TDI,TCK-TCK and TDO-TDO connections.

I am trying to use JTAG to burn the ESP32 program, but the following error occurs. How to solve this problem?

Thank you very much for your reply. I went through the steps again, but I still couldn't. I also went to understand the solution of GitHub. Our mistakes are not the same. I use the espressif's official circuit board, and his solution is not suitable for me.

I also found a forum response from 2019 that I think is the most similar error to mine.(https://esp32.com/viewtopic.php?f=13&t= ... 837#p49837)
I was using the WROOM module. The response said "WROOM module comes with AT command app" and the solution was to download the app in a different way. Does this mean ESP32 can't be downloaded using JTAG?
