Support for Raspberry pi 4

[spicalous]

Describe the bug Trying to use this library on raspberry pi4, but there are no events from library Running through troubleshooting wiki, I found some differences on my raspberry pi 4

To Reproduce Running a simple unit test

@Slf4j
class HIDTest {

   @Test
   void hidTestAutoStartFalse(TestInfo testInfo) {
      HidServicesSpecification specification = new HidServicesSpecification();
      specification.setAutoStart(false);

      TestHidListener hidListener = new TestHidListener();
      HidServices hidServices = HidManager.getHidServices(specification);
      hidServices.addHidServicesListener(hidListener);
      hidServices.start();
      List<HidDevice> devices = hidServices.getAttachedHidDevices();
      for (HidDevice device : devices) {
         log.info("{} Startup info device=\"{}\"", testInfo.getDisplayName(), device);
      }
   }

   @Slf4j
   private static class TestHidListener implements HidServicesListener {

      @Override
      public void hidDeviceAttached(HidServicesEvent event) {
         log.info("hidDeviceAttached event={}", event);
      }

      @Override
      public void hidDeviceDetached(HidServicesEvent event) {
         log.info("hidDeviceDetached event={}", event);
      }

      @Override
      public void hidFailure(HidServicesEvent event) {
         log.info("hidFailure event={}", event);
      }
   }

}

Expected behavior Events to be published and logged

Additional info

$ uname -a
Linux ubuntu 5.15.0-1021-raspi #23-Ubuntu SMP PREEMPT Fri Nov 25 15:27:43 UTC 2022 aarch64 aarch64 aarch64 GNU/Linux

$ lsb_release -a
No LSB modules are available.

I noticed there is an arm section in the https://github.com/gary-rowe/hid4java/wiki/Troubleshooting#arm guide

However my path for this file is different

$ find . -name 'libudev.so.1'
./usr/lib/aarch64-linux-gnu/libudev.so.1

Should I create a symlink by tweaking the path? e.g. sudo ln -sf /usr/lib/aarch64-linux-gnu/libudev.so.1 /lib/arm-linux-gnueabihf/libudev.so.0?

Sorry for a complete noob question but is there somewhere further I can check logs? At the os level for example?

Tried both below with no luck, but I'm pretty much shooting in the dark :smiling_face_with_tear:

sudo ln -sf /usr/lib/aarch64-linux-gnu/libudev.so.1 /lib/arm-linux-gnueabihf/libudev.so.0
sudo ln -sf /usr/lib/aarch64-linux-gnu/libudev.so.1 /lib/aarch64-linux-gnu/libudev.so.0

AFAIU there is no support for the hidapi binaries inside the distribution for linux-aarch64

The develop branch contains (in src/main/resources):

darwin-aarch64  linux-amd64 linux-x86-64    win32-x86
darwin-x86-64   linux-arm   win32-aarch64   win32-x86-64

@spicalous have you resolved the issue? I am facing similar situation
