Hi All,
I am working on WDM based USB Driver which controls the functionality of
Mass storage devices.
We have one requirement to print URBs and IRPs which we are passing to Lower
Drivers. For this we have to pass all URBs which we are preparing for lower
Driver to Application.
I am planning to do the same with WMI. Is it a good approach?
I have studied a little and understood about how to generate event in
Kernel Mode driver using *IoWMIWriteEvent *which queue the events.
Can any body tell how to access these events in Application(MFC based)?
Thnaks and Regards
Sunil
Enough is very heavy weight for this. Wmi events are targeted at infrequent small buffers. You should use an inverted call here by pending app io to the driver and completing it when you have an urb to report.
