I installed Ubuntu 16.04 on my laptop (additional HD).
As there are no linux drivers available on Atik service pages I switched to indilib.org - Downloads- Ubuntu-
and installed INDI Library stable release and Kstars-bleeding.
Result: No Atik cameras detected.Power on?
After installing Nightly PPA builds.
Result: Same report!
Under Windows 10 Horizon II works flawles with Atik Programs (Infinity, Dusk) or with ASCOM (Phd2).
