The thread 0x1988 has exited with code 0 (0x0).

Question

I am using the LibUsbDotNet to do some sniffing on USB ports. I get the following error in the output window The thread 0x1988 has exited with code 0 (0x0). Apparantly some thread is being aborted and immediately after this I stop getting the Device Connected, Device Removed messages. Does anyone know a precise way to find out where this is coming from ? Perhaps I could find a place where its originating? I have no information about this whatsoever. Thanks in advance.
