pyocd 0.36.0 version in python 3.12.2 can't find stlink v2 probe

[3x00]

I test pyocd 0.36.0 in pytho 3.9.6 is works, it can find my stlink-v2 probe
pyocd 0.35.0 in python 3.11.0 is works too
when I install pyocd on 3.12.2 which pyocd version is 0.36.0, use pyocd list return No available debug probes are connected
the step of install is same

@3x00 do you have a generic stlink-v2 probe, and if so what mcu is on the probe?

I had tried daplink and jlink, they can works.
python is 3.12.2 and pyocd is 0.36.0

This is an issue caused by libusb-package not providing the wheel for Python 3.12 .
If Python 3.12 is in use, pip will try to build libusb-1.0.dll .
For this build to complete successfully on the Windows platform,
VisualStudio must be properly installed on your local PC environment.
Otherwise pip will install libusb-package without libusb-1.0.dll .

The workaround is to manually get libusb-1.0.dll and place it where it should be.
https://github.com/libusb/libusb/releases/tag/v1.0.27
Put it to C:\Windows\System32\libusb-1.0.dll if you are not certain where to.
