"Recording... Remaining images" communication problem on 5D MK IV

WimVanCraen — Fri, 22 Nov 2019 09:30:11 GMT

I've searched for the same issue, found those 2:

https://community.usa.canon.com/t5/EOS-Rebel/Camera-locks-up-recording-message/m-p/159070/highlight/true#M10191

https://community.usa.canon.com/t5/EOS/Turning-off-camera-SD-Card-Access-Lamp-Recording/m-p/271245/highlight/true#M38045

Which are simular to my problem, but mine is still another case.

So, situation:

Have 5D Mark IV installed
Without mermory card
But with it's USB 3.0 cable connected
To a Win10 Dell Optiplex
On a SuperSpeed USB port directly on the motherboard
Taking several pictures after each other. This as:
- F.e. 5 image in a row
- Next 5 images 10-15s later

But sometimes I see that the communication is lost. Sometimes it restores itself, but even then I have to redo my image sequence again. Sometimes it won't work anymore.
What could help is repower the camera. But when I turn off the Canon, the "Recording... Remaining images" messages appears:

It's not useful to wait until the message is gone. The only thing that works, is to remove the USB cable from the camera. The message will disappear and the camera will be turned off.

After this, I can communicate again with my camera.

Any idea what can cause this issue? And how I can solved it? Nothing that I just use the USB cable and not memory card.

If not clear, please ask 🙂

Greeings,

So many factors here that might come into play.

What I think.

Buffering or transfer speed of the connection. First few pictures transfer , then the buffer fills and the images cannot be transferred fast enough to the storage source. The connection drops, fails and/or resets.

The camera only has so much buffer, I don't know what this is off the top of my head, but might you be exceeding the capacity with the transfer being unable to keep up with the flow of data? I don't use my camera like this, but believe this might be related to your issue.

What application is running the tether on the PC?

@shadowsports

Was also my idea. I've installed now a PCIe USB 3.0 board, as well as a power USB 3.0 extention cable of 5m.

I will see the results soon

@Waddizzle

I use a tool wrapped around the canon dlls using the SDK commands.

I am not going to be able to help you when it comes to custom software. Good luck!

Seems like the hardware adaptation is fixing the issue for now. No communication problems occurred anymore

Did you found a solution to fix it yet? I have a problem exactly like you but it happened on my MacbookPro even a new M4 version. I try different cable and adapter but it appears the same way when took continues like 8-10 photos.

It seems you're experiencing an issue with communication loss between your Canon 5D Mark IV and the PC when using the USB cable without the memory card. This could be due to several factors:

USB Cable or Port Issue: Even though you're using a SuperSpeed USB port, the cable or port could be causing intermittent connectivity. Try a different USB 3.0 cable or port to see if the issue persists.
Camera Firmware: Ensure your Canon 5D Mark IV has the latest firmware installed, as updates can resolve communication issues.
Power Settings: Check the power settings on your Windows 10 PC. Some USB ports may turn off to save power, causing communication issues. Disable "USB selective suspend" in the power options settings.
Camera Settings: Double-check your camera's USB settings. Some Canon cameras have settings for remote shooting or USB connection modes that might need adjustment.
Canon Software or Driver Issue: Ensure that the Canon software or drivers you're using (like EOS Utility) are up to date, as they may resolve compatibility issues.

If these steps don't resolve the issue, contacting Canon support would be a good next step for further troubleshooting.

Hello, Tumeann, and welcome to the forum!

This thread is 5 years old and the OP found the issue.

"Seems like the hardware adaptation is fixing the issue for now. No communication problems occurred anymore"

This probably won't help you as the OP's problem was solved with a hardware replacement, plus they had a different OS. It would be to your advantage to start a new thread with as much info as you can provide.
