did you try them on the same commandline?

exiting gphoto2 also exists some of the modes needed.

gphoto2 --set-config bulb=1 --wait-event 100s --set-config bulb=0 --wait-event-and-download=5s

i think also the shutterspeed on camera needs to be in "bulb" setting already before doing this

I did try that, no error, but no response either. From what I could tell in the documentation, I don't think Nikon exposes the correct features to make blub work for their older cameras. The documentation says specifically bulb mode works for "newer nikon models". I'm not sure what qualifies as "newer", but I have a hunch the D3 isn't it.
