Hi there,
I have a machine that will not recognise any MTP Devices (Cameras, Phones, etc) because when the MTP Device driver tries to install it fails and returns the error:
The dependency service or group failed to start.
I have tried all of the commonly suggested solutions to try and fix this problem - unplugging and removing all USB devices from device manager, removing upper and lower filters from sections of the registry, trying the fixit repair program, trying to repair
windows updates, etc, but I fear my situation may be a little different
From looking at many solutions it seems that the MTP Device driver needs the "Windows Driver Foundation - User-mode Driver Framework" service to be running. I have tried to make this service automatic and manually start it but it returns error 1068: The
dependency or group failed to start. The service is dependent on Plug and Play (which is started in my services) and User Mode Driver Frameworks Platform Driver. User Mode Driver Frameworks Platform Driver is not in my list of services. Is this normal? I think this is causing the problem but I have no idea how to correct it. It seems that it uses the file wudfpf.sys to run which is present in my system32 folder. However it is not running in my
startup services (viewed in msconfig) or in my task manager.
One of my attempts to fix this meant I tried to install this update:
http://support.microsoft.com/kb/2685813/en-gb
But Windows tells me it is already installed. I wanted to uninstall it and re-install but it is not listed in my Installed Updates. It is in my Windows Update history though - twice! One says successful and the other says pending.
As mentioned earlier, trying to repair Windows Update had no effect.
I would really appreciate any help or suggestions anyone can provide.
Cheers.
