EOS R5 The camera was disconnected during downloading in EOS Utility

Windsun33 — Wed, 03 Aug 2022 12:44:02 GMT

Has anyone ever come up with a real solution for this error from the Windows 10 version of EOS Utility? Happens with my R5 and all the latest camera and computer updates. Tethered, using the Canon R5 supplied USB-C cable on the computers power port.

This is apparently NOT a new problem - did some searching and there are posts about it going back as far as 2010. How many images it will download before the error occurs varies - sometimes just 2 or 3, ocassionally as many as 20 - but it invariably gets the error at some point.

And yes I know I can just take the cards out and plug into PC, but that is just a work around. BTW, same problem with my 6DMk2, so not just the R5.

There are hardware and software prerequisites for the Canon software. Simply running Windows 10 does not fully meet the requirements. One commonly overlooked requirement is an Intel chipset. Another is using a USB port expander.

I have all that.

What exactly does that mean? If you are using a USB port expander, then that is probably the issue.

I connected the cable to my camera and a notebook. Fired up EOS utlity. Select images to download and hit enter. I was getting the message after downloading 10-20 images. I clicked on preferences -> basic settings and untick automatically display quick preview window. It seems to work as I downloaded the whole set of 35 images (raw and jpeg),

This doesn’t work. I had 410 images to download and couldn’t get more to transfer in the EOS utility, Windows File Manager or Lightroom Classic. Even after applying this ‘fix’. The solution is to get an external CF Express card reader. This also saves wear and tear in the camera’s USB port. Perhaps a future firmware update will fix it, but this seems to be an actual bug in the camera.

That didn’t work for me. I bought a CF Express external card reader.

Turn off auto shut down under Power Saving in settings. It defaults to 1 minute

That’s never been necessary with other Canon cameras. This might work but it shouldn’t be needed.

It does work, but even so it still disconnects after the 30 minute maximum for display shut down so you would have to set a timer and tap the shutter button before that lapsed. Find a card reader is the better way to go because it’s also faster but this is the solution to the original issue at hand

The problem for the OP seems to have been a USB port adapter. Many laptops and home-brewed Windows PCs make use of them. Try using a different USB port, preferably one that comes directly from the motherboard.

[EDIT] BTW, the OP reported the same issue with two different cameras with the same Windows computer.

The OP’s problem is not the cameras or the Canon app. If it were, then thousands of people would be reporting the same issue and they’re not. Time to look at your PCs.

I agree with Waddizzle here.

Recounting the times I've transferred 300, 400 and 500+ photos in a single sitting, I have never experienced this behavior. Multiple powershots, T6s, 6D2 and R5 C. Using a USB cable in conjunction with the EOS Utility. I have also used a cable and windows explorer without the EU. I've not needed to make changes to a camera's settings either. More recently I use a card reader 90% of the time.

A computer with limited resources (processing power, memory, AMD chipset) outdated drivers, or using a hub could all be causes for this. An inferior data cable, memory card quality or card with bad formatting might also be cause. I don't have a way to reproduce this phenomenon as its never happened to me.

Today is May 2023 and this problem is still ongoing. I have this problem since I bought my R7 in August 2022. It is pretty annoying. It happens on Win11, eos utility ver. 3.16.10.8, camera R7 firmware 1.3.0 connected via usb-c cable.

Greetings,

Since the thread's starter was using an R5 and you are using a different camera, and possibly a different operating system and hardware, etc, I would suggest starting your own thread.

Please incluse information specific to your situation or environment.

Hardware being used

Operating system (version and build)

How the camera is connected and to what

Any error messages or observations that might help everyone better understand your issue.

As I said back in 2022, a $45 CF Express card reader works well and saves a lot of wear on the camera’s usb port. I put the SD cards from my R6 into the notebook’s built in reader and, again, no problems. Even with the external reader, there’s a lot of heat generated when reading large numbers of massive data files and I suspect that this is the problem. The camera is shutting down the operation to protect itself. And mine has an upgraded heat sink installed for long video shots. So why risk the camera, that costs you so much, when there’s a relatively cheap external card reader available?

It’s not worth risking the camera or your images. Get the external reader.

I specially registered to help someone with such a problem. Most likely, this error occurs in those who take photos on a laptop. There is no such error on the PC. all because of the lack of power from the laptop battery, as I understand it, and if you connect the power cable to the laptop and simultaneously upload photos to it, there will be no error and all photos will chip in. So try it

I was using it plugged in. And the USB port provides the standard 5V power supply. I haven’t tried it with the Thunderbolt 4 port on my new laptop because the card reader is a much better solution. The cards get quite hot during high speed data transfer and I see no reason to subject the (very) expensive dive camera to that.
