I have updated indilib on my RPi2 today.
1. sx_ccd_test (1.12) doesn't show any errors now, only bunch of OK's and numbers (that's good I guess).
2. "indiserver -vv indi_sx_ccd" starts without problems
3. AI 2.0(59) and 2.1(90) connects to SX-825 on RPi2-indiserver without any issues and camera is fully operational
4. Test with lodestar x2 connected - also no problem, everything works
