The camera cannot be connected with a computer / The computer does not recognize the camera (EOS-1D Mark IV)


If the camera cannot be connected to a computer, it may be due to the following reasons. Therefore, please check the following items in order to find the cause of the problem.

1. The camera is not connected properly to the computer with the supplied USB cable

To connect the camera to a computer, use the supplied USB cable. For details on how to connect the camera to a computer, please refer to How to connect the camera to a computer using a USB cable (EOS-1D Mark IV).

2. The camera is not recognized by EOS Utility

If the camera is not recognized by the supplied software, please check whether any of the following cases may be a remedy to the problem.
  • The supported software version may differ depending on the camera you use and the operating system installed on the computer.(Version 2.7 or later is supported.)
  • When using a camera or computer that differs from the model used initially, please download the supported version of EOS Utility. Versions of the EOS Utility Updater for a variety of cameras/operating systems can be downloaded from the Canon homepage.
  • EOS Utility does not operate correctly on a computer if its system requirements does not meet. Use EOS Utility on a computer with compatible system requirements. For details on system requirements that are compatible with the application, please refer to the Related Information section.
  • EOS Utility and the camera may not communicate normally with a cable other than the EOS DIGITAL camera-dedicated Canon interface cable. Connect your camera and computer directly with the interface cable provided with your camera. Do not connect the camera via a hub; doing so may prevent EOS Utility and your camera from communicating normally.
  • If there is insufficient charge left in the camera battery, the camera cannot communicate with EOS Utility. In this case, replace the battery with a charged one, or use an AC adapter kit ACK-E4 (Separately available).Your computer does not supply power to the camera through the interface cable.

3. CameraWindow is being used

Your camera does not support CameraWindow. If you are using CameraWindow, please install and use the EOS Utility application supplied with the camera.
If your computer does not meet the system requirements of EOS Utility, you can also download images by using the computer's card slot, or commercially available card readers.
For details on how to download images by using a card reader, please refer to the software's instruction manual (included on the CD-ROM).
