I own a QSI583wsg, but when I try to connect using Indi I get the error:
2017-06-29T18:15:20: Error: put_Connected(true) failed. 0x0:Cannot open camera connection.

or

I am running the latest virtual machine and I updated via apt-get the latest QSI driver. Virtualbox correctly detects the USB Device.
I am running Kstars/Ekos as ekos user and I already checked the FAQ related to CCDs.
I assumed you already installed QSI driver on the host machine? Then there shouldn't be a problem, I have the same camera. Make sure it is powered and fan running.
