Hi there,
I've got a problem with Windows 8.1 not recognizing my 5D III properly. In the device manager "Canon Digital Camera" has this yellow warning sign and code:
The drivers for this device are not installed. (Code 28)
There are no compatible drivers for this device.
Does anyone have an idea how to fix this? I want to calibrate my lenses with Focal..
Did you install the Canon Software from the disc that shipped with your camera?
Canon models use a PTP Protocol to communicate with the Operating System for transferring images, etc., and the EOS Utility Software on the disc that shipped with it is needed before Windows will be able to communicate with the camera (if you install everything on the disc, the EOS Utility Software will also be installed)..
You can download the latest EOS Utility 2.4 Updater from Canon's web site from the downloads section for your camera model here if you want an even newer version of it, or the version you installed is not working correctly with Win 8.1

Pick Windows 8.1(x64) from the drop down list of Operating Systems, then expand the "Software" section and you'll see it (EOS Utility 2.4 Updater)
Expand the EOS Utility Updater entry (use the + key), and you'll see this description for it:
"
EOS Utility is an application that brings together all of the functions required to communicate with the camera. Functions for downloading and displaying images, remote shooting, and camera control of each setting when an EOS DIGITAL camera is connecte..."
But, note that you'll need to install the version of the software from the disc that shipped with your camera before that updater will work to get the latest 2.4 release of it.
So, you really need to locate the disc that shopped with your camera for starters if you haven't already installed it, and install the software from that disc (which will include the EOS Utility software that is needed before Windows will transfer photos from it). . Then, you can update it to the latest version (if needed if the old version isn't working correctly with Win 8.1) using the EOS Utility Updater that you can download, as mentioned above.
For some reason, Canon never posts the full version of the EOS Utility software online (only a utility that can update it to a newer release if it's already installed from the disc that shipped with the camera), and Windows and third party software tools both rely on it being installed for communicating with newer Canon models.
