Error: libusb_open() failed with LIBUSB_ERROR_NOT_FOUND (IDFGH-9317) (OCD-709)

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

I have custom installation of esp-idf in folder d:\espidf and toolchain in d:\espidfTchain in Windows 10.
Everything works fine except openocd.
I get the following error:

Open On-Chip Debugger v0.11.0-esp32-20221026 (2022-10-26-14:48)

For bug reports, read

Error: Unknown target arch!

Getting some hint from here where it is mentioned:

To use binaries build locally from sources, change the path to OpenOCD executable to src/openocd and set the OPENOCD_SCRIPTS environment variable so that OpenOCD can find the configuration files. For Linux and macOS:

For Windows:
cd %USERPROFILE%\esp\openocd-esp32
set "OPENOCD_SCRIPTS=%CD%\tcl"
Example of invoking OpenOCD build locally from sources,
Windows:
src\openocd -f board/esp32c3-builtin.cfg_

What should be the paths in my case in commands

cd %USERPROFILE%\esp\openocd-esp32
set "OPENOCD_SCRIPTS=%CD%\tcl"
and
src\openocd -f board/esp32c3-builtin.cfg

@Zeni241 Your problem looks like a driver issue. Please check this https://docs.espressif.com/projects/esp-idf/en/v5.0/esp32c3/api-guides/jtag-debugging/configure-builtin-jtag.html#configure-usb-drivers

[erhankur]

@Zeni241 Closing this one. You can reopen it if you have any other issues. Also please check previous driver issues. You will find something helpful for you.

I had to follow this guide to get it to work:

https://community.platformio.org/t/esp32-pio-unified-debugger/4541/20

[Tomblarom]

@torkleyy Yes that solved it dor me! Thanks :) NOTE: zadiag had to be executed as admin!

[SpaceCheetah]

Following that guide just led to it not working at all, had to roll back to the windows ones. With those, I can flash with idf.py flash, but OpenOCD fails with error not found.

is there no fix to this? the zadiag solution is only for chips without an on-chip debugger.....I'm also encountering this problem
