Hi,

I have successfully built the driver and .sys was generated. When i specify the .sys file the OSR driver loader and press register service button, it gives successfully registered. But when i press start service button, it says “The system cannot find specified device file”.

Please help.

What type of driver is this? Only legacy drivers can be installed and
started with the tool.

I was trying windows filter driver (kmdf). It is a simple skeleton driver with only kdprint statements inside the functions.

Use an inf (inx) file, the kmdf toaster sample has one for a filter, just
change it to reflect the device class you are filtering.
