Error loading libusb4java

This is the first time I'm trying to use this on Mac, so no history of success. It's a M1 processor and trying to connect through USB Cable using NS-USBLoader v7.0 for M1.

Have a 19.0.2 Java Version

liadias@Lias-MacBook-Air Downloads % java --version
java 19.0.2 2023-01-17 Java(TM) SE Runtime Environment (build 19.0.2+7-44) Java HotSpot(TM) 64-Bit Server VM (build 19.0.2+7-44, mixed mode, sharing)

And got the following error on clicking 'Upload to NS' after selecting NSP file.

liadias@Lias-MacBook-Air Downloads % java -jar ns-usbloader-7.0-m1.jar

It's running on a 15.0.1 Firmware, Hekate 6.0.1.

Can anyone help me with this error?

Could you please check if this build works for you?

Fixed this issue for me with this - brew install libusb, @developersu might be worth making this a required dependency in the readme!

It should not be a dependency. This library already compiled for apple's aarch64 and added inside jar. It has to be picked up automatically on application startup as it's already done for another platforms.

That's why I'm asking to check another build.

I checked your other build and it failed with the same error.

paperschool avatar Feb 16 '23 20:02 paperschool

Sorry for delaying a reply, but it hasn't worked. Got the same error.

@lia-dias thank you! Please install libusb via brew install libusb and it will be working. Information about what brew is: https://brew.sh

Will fix this a bit later.

No problem. The brew method worked pretty well for me, thank you. When a new release fixing this is out, I'll try again and let you know.
