After I
upgraded to windows 10 and then promptly
uninstalled it a number of issues started to surface with the
Windows 7 installation that weren't there previously. One of these was that whenever the digital camera, a
Canon IXY 220F, was connected to the computer, it would not be recognised and would have a yellow exclamation mark next to it in
Device Manager. Uninstalling the camera in
Device Manager and reconnecting it to the computer would fix the problem temporarily, but after a restart the camera would not be recognised again. After digging through the
Event Viewer I was able to find the cause of this problem and found a way to fix it.
This is what
Device Manager was showing...
The
Event Viewer had a bit more information. These two events came up at the moment the camera was plugged in...
So what are these
WUDFRd and
WUDFPf references? They are to do with the
'Windows Driver Foundation - User-mode Driver Framework' service. Sure enough when I opened the
Services Manager, this service was not running and was set to manual start!
The
Services Manager is started by running
services.msc from the
Start Menu.
The solution is to double click this service and set its start type to Automatic, as shown below. Click
Start or restart the computer and the service should be running.
Sure enough, after a reboot, plugging in the camera produced expected results - the camera was recognised and I could import images from it.
