I am unable to connect my camera since the changeover to Fedora 24 with indi 1.2.0.
The connection works with the filter wheel (indi_sx_wheel).
But neither with the SX Lodestar, nor with the SX-694, both through indi_sx_ccd.
Adding debug options I see these messages :
2016-07-19T17:26:17: Driver indi_sx_ccd: sxOpen: libusb_open -> LIBUSB_ERROR_IO
And from /var/log/messages :

Can you also try with the packages? I cannot test SX as I don't have one. But if it is really a bug in Fedora libusb you could also report it here bugzilla.redhat.com
I tried with the official version. It does not work.
I also tried on another laptop with Fedora 24. Same result.
It seems to be the version of libusb that is involved
The problem becomes more complex
On a Fedora 23 with the same kernel (4.6.4) and the same libusbx, the camera works.
(and of course the same official version of indi-sx).
So the problem is elsewhere in the Fedora 24 ...
