 However that solution only works with comtypes version 0.2.1. Any
 newer version will result in the events not registering.

I've looked up the thread in the forum.  A user codenamed 'kitsu' wrote:

Note that there is a error in the comtypes 0.3.2 GetEvents function which
causes it to miss all events. I've reported it to the mailing list, but
until it is fixed use comtypes 0.2.1.

I have not found the 'report' he mentions on the mailing list.
Dois the code snippet that he posted here
  http://www.3dconnexion.com/forum/viewtopic.php?t=984start=33
work with comtypes 0.2.1, and not with later comtypes?

 This is the output I get from the GetEvents() function when using
 version 0.2.1:

  I believe, that this is enough output, because I believe the line
  DEBUG:comtypes:Release POINTER(ISensor) ptr=0x9f2170 at c14d50
  shows, where the bug originates. If you need any further testing, I
  would be glad to help.

Does it work when you keep a reference to the sensor object?  Something like 
this:

  import logging logging.basicConfig(level=logging.DEBUG) from
  comtypes.client import * x = CreateObject(TDxInput.Device) 
  x.Connect()
0
  s = x.sensor test = ShowEvents(s)
