OK, I had a closer look.  Kernel 4.9.6-r1 is not the problem on at least two 
boxen I just checked - I also tried a Macbook which keeps crashing at boot 
time with this kernel, but that's for another post.

The USB problem is related to the latest updates I ran, which also coincided 
with the kernel upgrade and this put me off the scent.  I booted into 4.4.39 
and the problem was still there on two different PCs.

I also booted into two different desktop managers, Plasma and Enlightenment.  
The problem remained with both of them, whether I used KDE apps to mount the 
USB stick or not.

As I mentioned, when I use pmount on the CLI I can mount the device.  However, 
when I used udisksctl, I got this:

$ udisksctl mount -b /dev/sdb
==== AUTHENTICATING FOR org.freedesktop.udisks2.filesystem-mount ===
Authentication is required to mount Crucial Gizmo! overdrive (/dev/sdb)

What?!  This comes up with plain users, and users in the wheel group.  This 
makes me think the problem may be polkit related.  These are the packages I 
emerged last weekend:
