Uploading to STM32F104C8 via ST-Link - LIBUSB_ERROR_ACCESS

I’ve seen other threads on this forum, but nothing from that helped me.

The particular one I’m refering to is (SOLVED) Cannot Upload to STM32F103 "BluePill" using ST Link on Nucleo Board - #28 by Hop. The situation there is pretty similiar to works, Arduino IDE upload works, OpenOCD does not find the device.

@slesingrpe

I downloaded official and lastest drivers from ST.com inluding the firmware for ST-link adapter.

Was there any old version installed before that that you uninstalled?

@slesingrpe

For me it is wondering that Arduino IDE have no issues with using ST-link with same driver versions that is not possible for PlatformIO to work with.

AFAIK it also uses a different program to flash the firmware, STM32CubeProgrammer CLI, as opposed to OpenOCD. But with the latest driver, both shouhld work.
