Usb mouse driver and Wait Wake - Revisit

NTDEV
1

My device has mouclass for upper edge and usbd for lower edge.

Here is a logdump with the following line in it:

144: FxPkgPnp::Dispatch - WDFDEVICE 0x7990EFF8 !devobj 0x8AD68718 IRP_MJ_POWER, 0x00000000(IRP_MN_WAIT_WAKE) IRP 0x8C17EE70 for PowerSystemUnspecified (S-1)

Does this log indicate request into or out of my device stack location?

  • USB bus trace does not show SET_FEATURE REMOTE_WAKE sent to device.
  • Event tracing of the USB stack did not show wait wake activity.

Who is aborting/failing this request?
Thanks,

Shows into the driver. Are you marking yourself as a filter, or at least turning off power policy ownership? Why are you writing your own mouse port instead of leveraging usb hid?

I call WdfFdoInitSetFilter(DeviceInit);

I use hid stack for many other products. This hardware for many historical reasons stays in the mouse stack. So I need to learn what holds this request back.

thanks,

If you want to see when the WW irp is completed, register a WDM preprocess routine for IRP_MJ_POWER/IRP_MN_WAIT_WAKE and when it gets called, set a completion routine, dispatch it back to KMDF and see what is happening.

I registered a WDM preprocess routine for IRP_MJ_POWER/IRP_MN_WAIT_WAKE, and set a
completion routine.

On entry to sleep I get

WaitWakeIrpCompletionRoutine Request failed STATUS_POWER_STATE_INVALID.

What do I chase now?

thanks,

On win7 I would use netmon and start creating trace logs of the core stack (the usb team blog has instructions on how to do this) and see what happens
