Thank you for working on the OM-D interface! I have had so many issues with my Stellarmate OS lately that I was about to give up on it. I found out my Pi B+ I bought in December was defective which added to my frustrations. After replacing the board and reloading the Stelarmate OS I am now having more success with testing. Tonight I was able to get bulb mode working with my OM-D E-M5. I was also able to get this working after downloading just the Stellarmate updates, so the bulb mode fix seems to be in place in the regular updates. Anyway if you have luck with the Pentax interface, then I will be beyond ecstatic!

If you want to try it, it has been merged into the official repository ( github.com/gphoto/libgphoto2/pull/394 )

This is what the "Shutter Release Port" is for in the GPhoto driver. Just find out what port the serial shutter release port is using and put that in. Is it /dev/ttyUSB0 or 1 or something else? what does <strong>dmesg</strong> say when you insert the cable?
Does Ekos support the serial shutter if a camera in not connected via USB? I just want to simplify things by using Ekos to Guide, Dither, and Trigger the shutter release with a USB serial cable. I thought from the description for Gphoto2 it would do this, but after some tinkering I see it does not which is why it is not detecting my serial release. My Olympus only has 1 USB port which can either be used for a computer connection or a remote shutter release, so I cannot do both at the same time.
Is there a way to add a stand alone serial shutter control to Ekos without having a camera connected?

sudo apt-get -y install gphoto2
gphoto2 --debug --debug-logfile=gphoto.txt --summary
Does it detect it?

It's working so far. The only thing is you have to take the shots in "Native" format, in "Fits" it's not working the driver is crashing during the "subframing" process (I suppose).
I'll make a Pull Request on the libgphoto2.
This helped me out with a BT GPS that I have! Thank you!
I plan on making the opto-isolated circuit on this website when I get this working:
Does Ekos need to see the circuit in order to detect the Comm port?
I am trying to setup a serial shutter release in Ekos using GPhoto (DSLR Cameras). When I try to connect to the serial cable I get the following error (attached picture):
Cannot Open Camera: Power OK?
In the info for GPhoto (DSLR Cameras) it show the following:
If your camera uses an external shutter release cable, make sure to indicate the port of the shutter release USB cable (usually /dev/ttyUSB0) in the Main Control tab of the GPhoto driver before connecting to the camera.
Additionaly, users may employ DSUSB/DSUSB2 from Shoestring Astronomy in order to control the shutter. Before you connect, the port field must be set to DSUSB.
I verified my Pi is seeing my USB Comm port and it is listed as /dev/ttyUSB0 when I have the terminal list devices.
Does anyone know what I could be doing wrong? I have not added the circuitry for the shutter release yet to the Comm port as I would like to verify GPHOTO sees the Comm port first.
Thank you for looking into this, Benjamin!
