libusb warnings

[Arno1]

I keep getting warnings when using STM32CubeProgrammer_CLI that usb devices are still referenced: libusb: warning [libusb_exit] device x.x still referenced. This is a bit annoying.

Hi Christian, could you post the solution here? I'm having the same issue on multiple PC's

Hello @Arno1,

 

The warnings issue is related to the version of libusb. To avoid these warnings, you can downgrade to version 1.0.23, which works fine. In the meantime, an internal ticket has been created (188089) and is being addressed by our team to resolve the issue from our side.

Thanks,

Amine.

Hi, any update on this issue? Downgrading libusb is a pain on our systems.

Hello @victorallume,

I recommend using the latest version of STM32CubeProgrammer, where the warning messages no longer appear.

Thanks,
Amine
