Error when running in a worker thread

When trying to run this package within a worker_threads worker, I get the following error when a device is added or removed:

I tried to create a minimal reproduction: https://github.com/kryops/usb-detection-issue-worker-threads

I also tried with the changes from #93 , but that did not make a difference either.

I am not sure this is the use case we want to dedicate support to but happy to accept a pull request to fix it.

If you want to ensure it keeps supported, add a test for it as well. Thanks for the small reproduction already!
