I have successfully setup a RPi 3 with KStars (full) and Ekos and tried it out briefly last night. I had always assumed that I needed a USB powered hub to connect peripherals to Pi, but out of interest I tried connecting the following straight to the Pi3's USB ports *without* any USB hub, and with a 2A power supply:
- Canon 450D DSLR (has its own power)
- QHY5L II Mono (drawing power from the Pi)
- EQDir (EQMod) cable (no power as the mount has its own power source)
With this setup, it appeared as though everything was actually working fine without the need for a powered USB hub. I was wondering if this sounds about right or whether I am missing something and definitely do need to put a USB in between the PI and peripherals?
