Alright I managed to reproduce a similar issue with a i1 Pro spectro
as sensor instead.

That looks like a very different problem - the USB read of the
raw measurement values has timed out. I've no idea why from
the log (USB hardware problem ?).

To follow-up on this point: on the same Atom D525 machine running
Linux Ubuntu 14.04 LTS instead of Windows 7.
Running the same stress test as found in the repository, maxing out
the CPU with 4 threads while taking readings from an i1 Pro connected
to the same USB port.

Under Windows, spotread fails after 4 readings (log 5)
On Linux, it went on up to 875 readings before asking for the sensor

I will retry this test tomorrow on a completely different computer for
good measure :)
