iPhone X "A device attached to the system is not functioning"

Hey Jacob!

I had this same issue to and tried this out and videos for me are able to be transferred to my PC from Iphone X now

Try This:

Settings > Photos > Where it says "Transfer to Mac or PC" Select "Keep Originals"

Hope it helps man!

Alec, I just wanted to say you are a genius. But you probably knew that already. I've been struggling with this for quite some time now and could never figure it out. Who knew it'd be such a simple setting in your phone to resolve this all.

I thought maybe it was Windows, maybe it was a faulty lightning cable so I tried multiple, or a bad USB port, or a bad driver. Tried what I thought was everything.

I have the 256GB iPhone X and record a lot of 4K 30FPS footage, and I've had the constant struggle exactly as described by OP. I gave up until I finally found this thread.

You are a life saver. Thank you Alec!

Hey regarding the issue with transfering pics and vids, i did that and it worked. However, some of the videos that transfered over would not play the video part, it only plays the audio of the video. I tried opening it with another video player and it said video is not encoded. I have an iphone 7 plus and a PC. *** I never had an issue until the recent update i did. Are u having the same issue?

This doesn’t help me. Still showing “A Device attached to the system is not functioning.” I’m transferring photos and Videos from my iPhone 8 Plus to WINDOWS PC.

One more thing I noticed. When I connect my iPhone to PC and open photo folder, iPhone Storage used memory keep increasing without doing anything.

Dont forget to restart iphone after making the settings

THIS WAS THE SOLUTION!

However, i can add the following information: if you have set it to AUTOMATIC than all files that cannot be "viewed" or "played" on your laptop/PC are not allowed to be copied. If you set it to KEEP ORIGINALS than you can copy those files on your laptop/pc but you will have "problems" viewing them because of "wrong" codec or version. I didn't find out how to solve the "viewing" problem but it's better to be able to save files on laptop/pc instead of loosing them or not being able to "backup" them.

Thank you sooooo much!!!!!!! Finally, I found the best solution to this irritating ios concern!! I've been having this problem since I got my iphoneX in January 2018 and the only way that I could transfer my 4k videos was (1) to change my computer storage device to SSD; (2) copy-paste 1 by 1; (3) limit my videos to < 1 minute; and (4) everytime that stupid error message, "device attached ..." pops up, I would always restart my handphone. But this week, all this couldn't work anymore (for whatever reason). Thank goodness I tried googling this issue again and voila; this solution from Alec (not even from Apple)!! THANK YOU SO MUCH!!!!!

Thankkkkkkkkkkk youuuuuuuuuuuuuuuuu sooooooooooooooooooo muchchchchchchchchchchchchchch!!!!!!!!!!!!!!!!!!!!

What kind of video player do you use? I use VLC Player and it worked perfectly fine, however the problem occurred when I tried to import the .MOV file to Adobe Premiere CC. But i found the solution by rename the file .MOV to .M4V

You can try it too to see if it is working 🙂

Correct this is an old solution that doesn't help me. I have to keep mine at Automatic so Premiere can play the video along with the audio.

I just keep re-plugging the the phone into the computer and eventually its able to copy over.

It's funny that you don't have this problem when moving them over to a MAC?

Hi Aslam Meman,

I have same Issue and after search on it in the net I found the same solution of Alecqz. Unfortunately, it does not solve the matter.

The solution was just change the cable, disconnect and connect the cable and restart my I phone. I tried these steps more than one time until I transfer all photos and videos from IPhone to PC (win 10 Pro).

Good Luck

You..are...THE...MAN!!! I've been shouting at my PC and iPhone for a while because it doesn't work!! Thank you, it worked right away, thank you, I don't need therapy anymore!!

...maybe I might need some from all the shouting..

Excellent, this not only fixed the problem, but doubled the copying speed; but as someone else commented, don't forget to restart your iPhone after changing the setting............ Thanks very much...............;-)))))))
