The second connection is not working properly

[WanManito]

In version 0.5.0, I tested read and write normally，
But here's what I did when I tried to free up resources

No exception was reported, but when the device was opened again, it was found to be null，as shown below ，

The normal situation would be as follows

Strangely enough, after I waited a while, the device was able to connect back to normal

I don't know if I release resources incorrectly or some other reason

That looks correct, but it may be that the resources are taking longer to be released than expected. Is it still happening with latest develop-SNAPSHOT version?

I dropped this solution in favor of USB4Java，I don't know if the solution you wrote supports Linux

[gary-rowe]

Thanks for getting back to me. hid4java does support Linux but if you've moved on to use usb4java instead then I'll close this issue for now.
