Hi, I am new to Windows Driver Development. First I tried the KmdfHelloWorld Driver, built the solution, and installed the driver using:
devcon.exe install KmdfHelloWorld.inf Root\KmdfHelloWorld. The device was successfully shown in Device Manager under Sample Drivers. The output message (from
KdPrintEx) was successfully shown in
WinDbg local kernel-mode debugging (but only after using
!dbgprint). Though, no output was shown in
But, if I try the same thing with Umdf Drivers, no output is shown, even after changing from
OutputDebugString. I may be wrong, but I guess Umdf drivers don't show output in kernel-mode debugging. Also, I want to use user-mode debugging for Umdf driver, but I don't know how to do that. It would be nice if everything could be done from inside Visual Studio only.
