EOS 5D MarkIV won't connect to laptop via USB port

alacey — Wed, 29 Apr 2020 21:42:48 GMT

My laptop won't fully recognize my camera when I plug into the USB port. The laptop will chime as if a connection has been made but then nothing happens, I can't find my camera in file explorer or when I open the Canon 3 Utility. The USB transfer cord that came with the camera works because I can connect the camera to my PC. The USB port on the laptop works because I successfully pulled images off a jump drive.

I have downloaded the newest EOS Utility and disabled the wifi and power off functions on my camera in attempts to get the laptop to recognize the camera.

I have read various forums but can't find the answer specific to my issue. I have asked this question of the Microscoft Community and downloaded and revised all the drivers to no avail. The last communication from Microsoft was to reach out to Canon, maybe for a driver?

Please help! I am so frustrated because I bought this laptop specifically for my camera and photography work.

Details:

Microsoft Surface Laptop 3 (arrived two weeks ago- brand new) / AMD Ryzen 5 processor / Windows 10 Home edition

Canon EOS 5D Mark IV (arrived two months ago - new)

Your problem is probably the AMD CPU. Read the "Supporting Documents" on the download page. There is a section that describes the hardware requirements, and it specifies Intel Core CPUs are required. I was not aware that there were any of the Microsoft Surface products that did not use an Intel processor.

Also there could be an issue with your USB ports on your surface tablet. The EOS Utility does not seem to work well with "USB Port Expanders".

Thanks for the heads up on processor issue. I couldn't find the support documents you mentioned on canon, so I googled it and came across this thread about 5dmkIV and AMD processors:

https://www.canonrumors.com/forum/index.php?threads/help-5div-losing-connection-to-usb-amd-ryzen-cpu.37892/

Many people have suggested getting a card reader to bypass the problem, but I had hoped to solve the problem. Guess it is time to buy a card reader.

Well **bleep**, been trying to figure this out for about the last 8 hours. This is really annoying. Although if you really want to work around this EOS Utility will work with an AMD processor if you set the camera to connect via wifi, although that seemed like it was pretty slow, was taking over a minute per image to download. Guess I need to find a 3.2 card reader.

Wi-Fi works because it takes the hardware out of the equation. USB port expanders are a bad thing, too.

I would not suspect the AMD processor as the first cause. Maybe it is but I doubt it. The best thing to do when you have a situation like this is to see if you can connect to another computer. If it does you know it is something in your computer but if it doesn't you know your computer is probably OK.

I would suspect the cable or the ports first. You do turn off wi-fi when you try?

Well cannot speak for the OP, but my 5D MK IV worked fine on my previous desktop (intel processor), still works fine on my laptop (intel processor). All of the USB ports both front and rear can recognize the memory card while inserted into a memory card reader with no issues, all of the USB ports can recognize a myriad of other items from my Samsung Galaxy S20 to my seagate external 5gb harddrive, which uses the same micro USB-B cable ( the one it came with was short so generally use the one from my 5D MK IV for this as well).

So as to your suspecting the cable or the ports, testing has ruled out the cable being bad (works with other devices fine, and works with the 5DMKIV on different computers), testing has ruled out any glaring overarching issues with the USB ports in general (they work fine with anything not Canon 5D MK IV, and work with the memory cards from the 5D MK IV via card reader, would like to try another model of Canon camera, but don't have one available). And I keep the wifi off by default to save battery, only turned the wifi on to see if it would connect to try and see if that would narrow down the problem.

Further if I plug the 5D MK IV in through my keyboards USB passthrough everything works as normal, except for the slow downloads compared to 3.1. I do have a USB PCIe card that I may install into one of the slots in the computer and see if that makes a difference later.

So after than and finding this issue being reported on multiple forums for over the last year, it really looks like Canon forgot to include AMD processor support on the 5D.

"So after than and finding this issue being reported on multiple forums for over the last year, it really looks like Canon forgot to include AMD processor support on the 5D."

The issue with AMD chipsets is not camera specific. The problem seems to be embeddd within the software itself.

I suspect that the EOS Utility software does not seem to follow the managed code model. The EOS tray icon has its' own startup setting for when a camera is detected. Instead of letting Windows 10 make the determination, the EOS Utili9ty bypasses the OS. IN fact, changing the OS startup setting seems to only confuse the EOS Utility, causing cameras to not be detected, or the user GUI Window not to launch.

The users who are reporting this type of issue always seem to have a home brewed PC running an AMD CPU. Even some commercial laptops, like some of the Acers, that run AMD chipsets have issues, too. My gut feeling is that the issue is probably with the USB ports used by the AMD chipsets, and not so much the CPU itself.

So just out of curiousity how would this be an issue with the USB ports, when they work fine for everything else? Are you saying that for some reason ASUS, GIGABYTE, MSI are all manufacturing faulty USB ports and only on AMD boards that only seems to cause an issue with Canon Cameras? The lowest common denominator seems to be Canon cameras and software. It seems like it would be something in the Canon camera firmware that isn't allowing it to communicate with AMD chipsets. even if I don't use the EOS Utility software, Windows will detect the camera is plugged in, detect that there are memory cards within the camera, but will not recognize that there are any images on the memory cards. But this clears up for some reason when used through a pass through USB like on my BlackWidow Kewboard.

It is a gut feeling. Your gut instincts might be correct, too.

Do I think there is something wrong with the ports? No. I think there is something wrong with how the Canon apps reference and access the ports. The Canon apps seem to make unmanaged function calls to the hardware, which make the apps hardware dependent and specific.

Thank you for weighing in and helping to troubleshoot. My markiv connects via USB port seamlessly on my PC. The issue is with new microsoft laptop failing to connect to camera via USB. Windows 10 has never recognized a connection to the camera.

Canon suport offered the following:

"Turn off wifi and check laptop power"

"In a case like this where one computer can recognize the camera and another cannot that indicates the issue is either related to operating system settings or security software settings."

"Triple check the EOS Utility software."

"One last thing to try getting the computer to give you a permission prompt in the EOS Utility."

"From what you describe it sounds like the USB connection itself may be dropping after it makes the initial pairing. This would be confirmed if you see a computer icon display on your camera's LCD screen when you make the initial connection but see it disappear shortly after. If you see the computer icon on the camera LCD screen and still cannot see the camera's memory card listed in your file explorer then that would indicate Windows is preventing data transfer from the device and this would mean there is some other conflict within Windows."

From the research I have been doing, it seems this is centered around PC's running an AMD processor. For some reason, either on Canons or AMDs end the USB ports will not recognize the images on the memory card. I have so far tested this on 5 PC's. 3 Intel processors, 2 AMD processors. All 5 have different motherboards, 4 were home built, and all 3 Intel Processors were different, both AMD PCs are using a Ryzen 9 3900x. All 3 of the Intel PCs work fine no issues. Both AMD PCs you cannot directly connect the camera through the USB ports, either front or rear. You can however connect them through a USB keyboard with USB 2.0 passthrough, such as a Razer Blackwidow, in which case it will work fine. It does not work however is you attempt to use a 3.1 USB hub to connect to a USB 3.1 port. There are posts about this issue going back over a year. Canon blames AMD/Motherboard manufactures they blame Canon. Personally I think it is some issue in the Canon firmware that they just don't want to fix, since the USB ports work fine for everything except the Canon camera. Looks like you're best bet for quick downloads is to sheel out for a USB 3.1 Memory Card reader, and just forget that the canon software even exists, since Canon doesn't seem to care about the issue.

Yes. Seems to be an AMD USB driver issue.

All PC's with Windows I assume? Seems AMD PC's with Linux have no trouble to detect 5D IV. Both what I have read and my own experience with older cameras like 6D, 7D, M5.
But of course, Canon EOS Utility will not work without a VirtualBox.

Have you tried Safe mode in Windows?

This doesn't help laptop users, but in case anyone is running into this issue on an AMD Ryzen desktop.

I built a Ryzen 3900x PC and couldn't get my 5D Mark IV to work in tethered mode. I had an existing USB 3.0 Expansion Card (ORICO PME-4U) laying around that I installed, and those ports seem to work just fine.

In Device manager, this is what I see for the AMD ports:

"AMD USB 3.10 eXtensible Host Controller - 1.10 (Microsoft)"

For the expansion card it shows up as:

"Fresco Logic USB 3.0 eXtensible Host Controller - 1.0 (Microsoft)"

My educated guess is that the camera doesn't like the AMD drivers for whatever reason. Very strange.

Thank you for this thread, I just did a new AMD 5900x build and my 5D MarkIV won't connect to it. My old build which have an intel processor is able to tether / read the camera just fine when directly connected to it. I'm just wondering, is this only a 5D MarkIV issue? or is any other EOS cameras having a connection issue with AMD processors?

Re: EOS 5D MarkIV won't connect to laptop via USB port

iceman2486 — Mon, 28 Dec 2020 04:18:17 GMT

From what I've been able to determine it's all Canon Cameras. Canon and AMD don't seem to want to work together to make the software work. Kind of annoying, but I ended up getting a high speed card reader that can transfer the files faster than from the camera anyway.

Re: EOS 5D MarkIV won't connect to laptop via USB port

wongster41 — Mon, 28 Dec 2020 06:05:22 GMT

I have a card reader so that's not the issue, I wanted to tether to my PC for studio shooting. Guess I'll have to use my intel PC for that, kinda annoyed Canon won't update their software to work with AMD processors.
