CAP_SUPPORTS_DETACH_KERNEL_DRIVER always FALSE

Environment:

• OS: Gentoo amd64
• Java version openJDK 11.0.5
• usb4java version 1.2.0 and 1.3.0

Bug description On Windows (x64) 7, 10, Linux (amd64) every time I check hasCapability(LibUsb.CAP_SUPPORTS_DETACH_KERNEL_DRIVER) I see false value.

However, the chain of kernelDriverActive(..) ?-> detachKernelDriver(...) -> do_the_job -> attachKernelDriver(...) works for me.

Also setAutoDetachKernelDriver(...) works as a charm.

I'm reading your documentation / examples and I don't understand, why should I check this CAP_SUPPORTS_DETACH_KERNEL_DRIVER? Could you please tell me on what platform it would return true? What is the best practice for this? Just don't check and use setAutoDetachKernelDriver(...) for every app without any pre-validations?

Thank you!

Reproduction System.out.println(LibUsb.hasCapability(LibUsb.CAP_SUPPORTS_DETACH_KERNEL_DRIVER));

Expected behavior Emm.. To be honest, now I'm not sure what should I expect. Please advise.
