What do you mean by assigned the device to VM? I didnt do anything like
that.
WUDFHost will get started when a UMDF device is detected and the driver
starts running.
In my case I’m getting the error ‘This device cannot start. (code 10)’. I’m
not sure whether the driver loaded successfully or not and why is it not
starting. You suggested me earlier to try debugging the driver and I’m stuck
up with debugging too!
I tried running the chkinf tool. Its giving the error “DriverCLSID is a
copy-paste from WDF Samples.”
The WDK documents are not clear enough for a mere beginner clearly explaing
the steps to be followed for customizing the samples. too many issues. I’m
sorry to say this. I’m really frustrated.
thanks.
