Thanks, Graeme.

Yeah, I went back and searched the list archive and did find another report of the same problem with RPi/Raspbian.  He said the problem wasn't present using an experimental version of Debian, so that points to something Raspbian is doing - either to the kernel or in userspace.  I may try a non-Raspbian kernel in a bit.  Will report back here so whatever I find will be available to/archived for others.

Hi,

I've just found that chartread also returns the same error as `spotread -e` 
when trying
to calibrate.  I was using Argyll on a RaspberryPi running Raspbian Jessie with 
the
precompiled/dist package.
I seem to recall someone else reporting this type of problem with the 
RaspberryPi.
It seemed to be related to the version of Operating System they were using,
and they worked around it by using a different one. So that hints that
RaspberryPi still have a bug in their USB driver code.
