Camera Suddenly stopped communicating with EOS Utility

[jodywagstaff]

my two canon's, 70D and 5Dmkii, will not communicate any longer with EOS Utility

Windows 10 pro - 10.0.18363

Intel i5-9600

z390 UD - motherboard

24 gigs ram

-- Installed Eos utility and connected my 70D.  It connected immediatly and started the EOS Utility.  I then used camera control to open a live view window, which i then linked into OBS to capture the video.  About 10 minutes later, while using obs, the image froze on the camera.  Now my 70D and My 5Dmkii will not communicate with EOS Utility. The cameras immediatly connect with windows and can be seen in the navigation tree.  I can view images on the SD and CF cards but EOS utility says to connect a camera.

I have uninstalled and reinstalled the EOS Utility app as welll as all other canon apps on this machine.

I have tried multiple cables, ports, and hubs.

I have disconnected all other usb devices.

I have tried eos 1, 2, and 3

Please if anyone can help with this, I would be very grateful.  My cameras are an integral part of my streaming set up and i am unable to proceed without them.

Thank you.

Try using system restore and revert to a point in time where the software "worked" in your environment.

I have a (Gigabyte)  Z390 Aorus Pro, which is a higher end model of what you have.  Its a "Home Brewed" pieced togther desktop.  Intel i9, 32GB of G-Skill RGB Ram, Samsung m.2, EVGA RTX2080 FTW3....  and windows 10 Pro...  The EOS Utility works fine.  All my installed applications work.  I'm not using any open source software.

Your issue appears to be software related and has nothing to do with the hardware platform.  Why not buy something like Premiere? 

Or there are numerous (other) Broadcast quality applications (which yes, cost money) but you can receive support for. 

We understand your point.  All motherboards are pretty much built in Taiwan or Malaysia..  Regardless of whose name goes on them.  Intel, Gigabyte, Asus, EVGA, Foxconn...  are the biggest OEM suppliers. 

I think the problem in your case though is software choice. 

I have 11 or 12 machines in the house. Desktops, laptops..  (Apple, HP, Lenovo, Dell, Asus, Gigabte, etc)  My desktops are never prebuilt and always assembled by me. I am in full agreement about open source software not being 100% compatible, reliable, etc.  Its free.

Maybe look at something paid and you'll have better luck with compatibility.

Thank you for the reply. I did try a system restore and it did work for me. There are still some issues with the EOS utility not recognizimg the camera but it seems to do with the various versions of the software.

I do use Premiere for editing. Obs is for streaming.

You might want to try using the version of EOSU that came within your camera.

If you don't have the CD that came with the camera you can download a digital disk image from the 70D support site. 

I have had situations where later versions of software wind up with incompatibilities with earlier products.
