I have tested as suggested, the driver is not crashing and it ends up in the usual yellow state, and gdb only reports the same information that is dumped to the indi log:

2019-01-12T11:04:05: Driver indi_canon_ccd: Number of cameras detected: 1.
2019-01-12T11:04:05: Driver indi_canon_ccd: Detected camera model Canon EOS 1100D on port usb:001,017

I attach an screenshot to show what happens in ekos and in the console

Is there a quick way to check with gdb where the driver is stuck? (sorry, my c programming skills are almost forgotten and rusty ...)
