Could not update ST-Link firmware with latest STLinkUpgrade on macOS Catalina with Java 14 because libusb not found.

[SElin.1]

Here is an error:

 java -jar STLinkUpgrade.jar
Exception in thread "main" java.lang.UnsatisfiedLinkError: /Users/yes/Downloads/stsw-link007/AllPlatforms/native/mac_x64/libSTLinkUSBDriver.dylib: dlopen(/Users/yes/Downloads/stsw-link007/AllPlatforms/native/mac_x64/libSTLinkUSBDriver.dylib, 1): Library not loaded: @rpath/libusb-1.0.0.dylib

I also tried to replace provided libusb with installed with brew without luck. So how can I upgrade firmware? Am I missing something?

Looks like ST-Link upgrade doesn't work with Java 14, if you have error above just downgrade java to 11.x

I am getting the same error. I tried running Java 11.0.8 and Java 8u261, and neither changed anything. Same error. My recently arrived STLINK-V3SET is running firmware V3J1M1B1S1, which is very old. Other suggestions?

I was eventually able to upgrade the firmware by running the windows ST-LinkUpgrade.exe from a Windows 10 VirtualBox VM. I found no way to successfully run the Java jar.

I had the exact same issue, using Java 8 worked for me.

Simply downgrading to Java 11 did not work for, but maybe downgrading to 11.0.3 might also work.
