USB2000+ not initialising #291
Description
I'm struggling to get pyseabreeze to work with my USB2000+ with the following script
import seabreeze
seabreeze.use('pyseabreeze')
import seabreeze.spectrometers as sb
spec = sb.Spectrometer.from_first_available()
See below for the stack trace. I have managed to get sensible looking spectra out of it with omnidriver, so not sure what's happening here, other than the obvious. I would note that I get an error about not being able to load non-linearity with omnidriver, not sure if this is related, or even unexpected for this model.
