I am almost done with my home observatory (Ikarus Observatory) and it is already working on Raspberry PI 2 and powered USB hub.
Of course the observatory is going to be a nice test bed for several equipment that I own. For example, I discovered guiding with ZWO ASI was not reliable and it returns an error after a minute or two (already contacted ZWO); similar issue with my QHY5LII. Everything else is working as expected, including my Lodestar & QSI CCDs.
EDIT: Ok Gerry informed me that QHY5 acts funny even with powered USB hub especially that the same hub powers 6 devices.
