Damn, such a facepalm. There is a lot of stuff plugged into the PI already, and it is hard to reach the free USB ports, so I used a USB A male to USB A female extender cable. And when I checked the journal, I could see this:

> Sep 16 08:05:50 OpenHAB kernel: usb 1-1.4: New USB device found, idVendor=090c, idProduct=1000

> Sep 16 08:05:51 OpenHAB kernel: usb 1-1.4: USB disconnect, device number 31

And this section kept repeating. Now I removed this damn extender cable, and now it appears to be working:

Although I don't see this being mounted automatically to any path.

Let me tell you want I am planning to use this for: my dad likes to listen to recorded programmes from the radio on his phone. At the moment, he has an old Samsung phone which still has an FM radio and only uses that to record radio programmes. There are no such services I know of where you can listen to past radio programmes where I live.  
I already have have a working Node-Red flow which can be programmed to record radio programmes (from internet radio source) and save them as mp3 on the PI. This piece I am working on should automatically copy these mp3 files to his phone when it is plugged into the PI. This is why I wanted to see if new USB devices are plugged in. But I realized that mobile phones will not be detected and USB mass storage devices immediately. Currently he has a Huawei Pxx phone. He is \>80 so I need a solution that is plug and play.

That might be because you aren't using standard Raspbian (at least that is what I deduce from the log). That might also be a factor in what was causing the SEGV error with the faulty cable. Even with a faulty cable `usb-detection` should not crash, assuming that is what was happening.
