Can you try to do the same thing with gphoto2 from the console?

Some further exploration of gphoto2 on the command line...
--trigger-capture --capture-tethered=#s or --wait-event-and-download=#s
this works but does NOT honor BULB (either camera exposure setting or the -B/--bulb option on command line
it WILL work in other camera exposure setting (for my Sony A6000 that is 1/4000 sec ... 30 sec)
use the SECONDS option in the command line and make it at least 7 seconds > camera exposure time
--capture-image-and-download
this works but ONLY camera exposure setting OTHER than BULB (for my Sony A6000 that is 1/4000 sec ... 30 sec)
--capture-image -B/--bulb --capture-tethered=#s or --wait-event-and-download=#s
this works
use the SECONDS option in the command line and make it at least 7 seconds > camera exposure time

The Sony A6000 uses LENR (long exposure noise reduction) by default. It has the effect of doubling the length of time it takes to save the image. If I turn LENR off indi_gphoto_ccd does manage to save and download the first image and the length of the exposure seems to have no effect. I can also cause the first image to be saved if I increase the timeout (gphoto_driver.cpp line 912) instead of turning LENR off, however as the exposure time increases I eventually hit the TIMEOUT failure.

How long would it take to save a 30-seconds exposure for example?
