I wouldn't believe that as an indicator one way or the other.

Here's a test for you to run:

   - unplug your USB-driven weather station.  Run just 3.9.1 with the 
   simulator driver.  I bet it works and is very stable.
   - switch back to your USB-driven weather station, making no other 
   changes.  See if it fails again.   I'm guessing it will.
   - If it does, it is either the fousb driver (possible), or lack of 
   sufficient power to the pi (far more likely)

Alternately, buy a Kill-a-watt and measure how much power the pi is 
actually drawing in both scenarios.

I have a pi3 running off SD that is loaded up with 'lots' of software and 
it is rock solid.  I have a second pi3 running off a laptop SSD card and it 
is very 'unstable'.   Same power supply on both.   My only conclusion is 
that the unstable one isn't getting enough power to drive the pi and 
external USB disk.   I'm guessing almost all of these fousb station issues 
we hear of for pi users are the same thing.  Just not enough power to drive 
much off the USB ports from the pi.
