	I'm using Ubuntu 14.04 Server on an i686 Dell/Wyse CX0 thin-client - 
usbhid-dump was available as part of usbhid-utils, if I am not mistaken.

	I do have the correct permissions for udev. The explore mode complains:

	I've ordered a second model (EBay, $25) - one to install into the car, 
and one to debug/test. It is possible to change some of the parameters 
of the device, using a Windows program. I have another CXO host with 
Windows on it that runs the Copeland Engineering software, with which I 
can compare if necessary.

	I expect it won't be hard to get this working with nut, and I'm happy 
to do a bunch of legwork (commit credits!) in order to get this thing 
working for my purposes - and I appreciate your help, Charles.
