    It's true that "most cameras" don't have a problem, but the Sony cameras do; but when I contacted Sony, they said it was exclusively an Apple problem. I told them I didn't think so, because by Nikon DSLR and Panasonic and Fuji P&S cameras all work fine. It's a problem with Sony. At that point they disconnected.


    Resetting the USB for unpowered in the camera does no good; and of course you can't run this camera with the power cord while trying to download, there's only one I/O port for both functions. So it's a powered USB hub or nothing.


    Sony is famous for this sort of thing, by the way. They supply a nifty movie utility with their cameras, but don't bother to tell you in the material, online, or anywhere else that it doesn't work with Apple OS.

    I do not have a problem with the Alpha 100 and 900 DSLRs.  I have not had the error message appear with either, and I connect them while powered from their internal battery.  Of course these are really Minolta cameras!


    I wonder if your Sony videos are compatible with utilities from other brands?  You may be able to freely download them from the manufacturer's websites.  Canon has utilities available, but do not see one for movies.


    There are Mac programs called iMovie and iMovie HD in my Applications folder.  Have you tried either?

    The Sony apps are useless with OS, so I now just open the folder, drag the file to the desktop and use native Apple apps.

    This may help, bought a new Nikon Coolpix S6200. Had previously not had trouble with the old Cannon I Had. Plugged in direct from camera using the USB cable and the Camera connector and got the dreaded, Accesory drawing too much power message. After fiddling for a while it somehow downloaded the pictures.

    We now follow the following procedure and have not had any problems


    Firstly check your camera to see if there is a setting saying Charge by computer. Set this to off, do not leave on automatic.


    Attach camera connection kit to iPad


    Attach USB cable to camera.


    Open pictures app on iPad


    Turn camera on


    Attach camera to iPad using the connector and USB cable.


    The camera will close the shutter and then download the pictures for importing.


    Now works every time.   I hope this helps someone !

    Thanks!  I was able to load pics to my iPad without a problem after turning the charge from computer feature off.

    I'm still looking for a solution to upload images from a CF card via a card-reader, through a usb hub, through the camera connection adapter, to the iPad Retina.  I read that a very few "unpowered" usb hubs work but can't seem to find one.  Can anyone confirm a system that works with CF cards in a card reader?  I don't want to use my Nikon camera.  PLEASE HELP!!!

  • Fred*M. Level 4 Level 4 (2,380 points)



    The only reason to use a USB hub, is so the hub will provide the power needed when the card reader draws too much current.  Obviously an un-powered hub is of no use for that.


    I have one CF-to-USB card reader that works with the camera connection kit on my iPad 2.  However, I also have others (including a couple universal adapters) that draw too much current.  They all work when using a powered hub.


    Of course you can not use a powered hub when no power is available.  This may be a dumb idea, but what about having a second camera that can be used as a CF card reader?  It would not even have to be the same brand as long as it takes the CF cards.  I understand all modern cameras use the same card format, and store images in a DCIM folder on the card.



  • johnjuniper Level 1 Level 1 (0 points)



    Thanks for this.

    I considered a second camera body but don't want to invest in one for this. My current 2nd body uses SD cards. 

    Can you tell me which card-reader you have that is compatible with the camera connection kit?  This may be an issue for me regardless, as I have the ipad retina and Apple may have downgraded the power restrictions permitted.

    Does any powered USB hub work?  I could make due with this even though it requires plugging in somewhere.


    Please advise.

    Thank you.

    My Compact Flash Card Reader that works with the Camera Connection Kit, seems to have no name!  It is a model CR-V7-UC.  My computer identifies it as being from Genesys Logic, Inc.  I have had it for several years, so it may no longer be available.


    Another option that might  work for you, is to obtain an SD-to-CF adapter.  I have one from Delkin Devices <>. You would remove the SD card from the adapter and read it using the Camera Connection Kit's SD card reader.  If you get one, be sure it is compatible with the SDHC standard.  Some such adapters do not work with SD cards over 2 GB.  (I have an old one like that made by Minolta.)


    The iPad 1 initially had a much higher current limit.  The limit was reduced by a subsequent iOS update.  In other words, it is limited by software not hardware.  As far as the Retina iPad having downgraded the power available, that is possible but I doubt it.


    I think most powered USB hubs will work, but you would need to try it to be sure.  Look for the cheapest you can find!

    Folks, my Nikon S9300 had the same problem.  All you do us use the Apple Camera kit and insert the SD card adapter, versus plugging the camera into the iPad - walah!!

    Just use. The SD card adapter and plug into the iPad, nothing else to do and problem solved.

    Actually guys the way to do it is not with a powered hub, but a NON- POWERED USB Hub.  Once connected you will not see the error message and it will detect the USB drive, granted that its formatted correctly and that the root folder is named DCIM.  Also any thing that needs to be transfered would have to be renamed as well.  For example the file structure only supports 8 characters, so your movie or picture will need to be renamed as such.  (MOVIE001.MOV )

    Why does Apple sell USB to Lightning connectors for USB cameras and won't let you use this connector for exactly this purpose I wonder? My wife just bought the Canon N and as we only had a 4GB micro SD and I brought my iPad anyhow I decided to buy the USB to lightning connector. Pretty useless if all that I get is the error message: "Device uses too much power"... I checked the menu on the camera but can't find a way to switch off "charging when connected to PC" either... Any progress on this subject?

    I have recently bought an Apple ipad camera connection kit which the guy at best buy told me would work.  I am only wanting this to use my memory stick/flashdrive at home with my Ipad.  I am a schoolteacher and need to be able towork on documents and such at home.  When I put the adapter in and plugged my flashdrive toit I received an error message about to much power and it would NOT work.  Can someone PLEASE help!!!@

  • Fred*M. Level 4 Level 4 (2,380 points)



    I do not think you can do what you want, even if there was no error message.  Using a camera memory card or a flash drive with the adapter set, is intended to work with the Photos App, and only works with files having 8 characters-plus-suffix names stored in a folder named DCIM.  (Files named something like IMG_0414.JPG or, can be read.)


    As far as the error message is concerned, you might try a flash drive or thumb drive from a different company.


    There is at least one product on the market that might work for you.  Take a look at a product called i-FlashDrive, which has both an adapter and an App to use with it.  One end of the adapter plugs into your computer's USB port to load files.  The other end plugs into the iPad to transfer the files.  <>
