   What I am about to describe may be an unrelated phenomenon:   
      
   I run a Pi4b in the Official Case with the Official Fan. [I don't   
   recommend that fan to anyone. It does not get much airflow unless the   
   case is propped open.]   
      
   The operation of the fan tends to build up a static charge throughout   
   the case's environment. When a USB device is plugged in, there is often   
   a brief static discharge, which can have an undesirable effect on the   
   Pi. I might get a screen glitch or a hang or a crash or a reboot,   
      
   I alleviate this problem by using an old unpowered Radio Shack USB hub.   
   This minimizes static buildup, and keeps any potential discharge some   
   distance from the Pi's circuit board.
