Last night I ran into the same problem again. My Canon camera became unresponsive and I got the same error message as reported by pcxz. Just now I managed to easily reproduce it. Simply connect the camera with a USB cable to a laptop or PC. Start KStars and Ekos. Start INDI and Ekos will detect the camera. In the INDO control panel, select the camera tab and click Disconnect. Unplug the USB cable and plug it back it. Click the Connect button and the error will appear:

2017-10-13T18:31:31: [ERROR] Can not open camera: Power OK? If camera is auto-mounted as external disk storage, please unmount it and disable auto-mount.
2017-10-13T18:31:31: [ERROR] Camera_get_config failed (-2): Bad parameters

I attach a verbose log in case it helps track down the issue.

In that case I cannot help you. That fixed my problem.

I had a similar problem with my Canon EOS 700D. I solved it by setting the Auto Power Off setting of the camera to Disable. This needs to be done on the camera itself and it is not an Ekos setting.

Modern Linux kernels don't support high bandwidth on USB2 anymore. For more details and how to patch your kernel, please see

OK I will share my experiences here as soon as the cable arrives. And yes, I am on astroforum.nl ;-)

I currently use a Prolific serial to usb converter cable and it works fine on Linux. However, I have troubles getting it to work on macos Sierra and high Sierra. I ordered the FTDI cable from the link I put in my previous comment. Fingers crossed ;-)

Thanks very much for the explanation! I am on Mac and Linux so I'll need to see if the FTDI chipset cables also work on those platforms. It looks like this one does at least work on Linux:

Thanks for the comment Elfe but I am confused now.

Jasem says using the EQMod driver won't affect guiding (i.e. I still need the ST-4 cable) but you say it replaces the ST-4 cable connection. So, do I need the ST-4 cable when guiding over an EQMod connection or not?

Also, how can I disconnect the hand controller when in PC Direct mode (i.e. using the EQMod driver) since the PC connection cable plugs into the hand controller?

I updated again and gave it another try. Doing so I discovered a configuration error. The aperture and focal length of the guiding telescope were wrong! So I corrected those and let Ekos guide for about 15 minutes. That went perfectly OK. Sorry to have bothered you with this. In any case, here is the log of tonight.

I was able to give it a try tonight and again, sorry, the calibration for the guiding failed. See the attached log file. Thanks again so very much for your support!

Ok I pulled the new version from your repo. Not sure if I can test tonight but otherwise tomorrow. Thanks a lot!

Hi Jasem,

Thanks very much for the suggestion to use the EQMod driver. I have tried this a few weeks ago (only for goto) and it works so I'll use that from now on. However, if I understand correctly this will not improve guiding, will it? The guiding commands are sent via the ST-4 cable, right?

As for your question about PHD2, no I don't use any additional configuration. In the PHD2 wizard I chose my guiding camera, chose On Camera for the mount and no AO and no ... sorry, forgot what the 4th option was. That's all.

Anyway, I'll setup the mount with the DSLR camera and ZWO guide camera again tonight and will enable logging for "Guide". I'll let you know the result afterwards.


Clear skies, Wouter

Hi,

This is my first post here. I searched this forum for hints to help me resolve my problem but I didn't find any :(

I have a SkyWatcher AZ-EQ6 mount that I connect to Ekos via the SynScan driver. This works ok for me. Once I do a manual align (I haven't tried the alignment module in Ekos yet) any object I instruct the mount to go to via KStars ends up at the center of the FOV. Great!

However, I have auto-guiding issues. I use a ZWO ASI120MC camera and I applied the USB2 patch so I get images on my Lubuntu 17.04 laptop running kstars-bleeding. Shooting darks is fine, capturing an image as well. But as soon as I start calibrating things go wrong. Calibration in RA so far always has gone OK but calibration in DEC not. As far as I understand Ekos will send guiding commands to the ZWO ccd camera which then passes them on to the mount via the ST-4 cable. The funny thing is that guiding doesn give any problems at all using PHD2!

Now, of course I could stick to using PHD2 for guiding and Ekos for the rest but still. What could be the problem? Polar alignment is ok as I stated above. The mount responds well to any button press on the handpad. And PHD2 is guiding like a charm. What could be the issue with Ekos?


Clear skies, Wouter
