Thanks a lot Kevin, I reimplemented the device lookup using the IOService discovery. We will probably switch to CoreHID API in the future, but currently all works perfectly!

Here is the minimal example. I forced 12 second delay between the closing the device and opening it again, that proves that it barely can be race condition. (If you have the FIDO device on your end, you can test it) The minimal example

Thanks for the reply, Kevin, I will try to make the minimal example today, but from what I have in the real application it's unlikely the race condition, since the device doesn't send input reports without prior output report. The use of CoreHID is possible, but our app is implemented is C++ and it will cause additional efforts for creating the bridge. Anyway I will consider this option, thank you!
