IOCTLS are not arrived after Standby

NTDEV
1

Hi,
I wrote keyboard filter driver, which has additional control device that
receives the IOCtl’s from user software.
Currently I met strange issue: after the computer returned after
Standby, IOCtl’s are not arrived to driver. I see that DeviceIoControl
functions is succeeded( returns TRUE ),
but driver do not receives any IOCTL.

Is there any idea, what is wrong in driver/software? What can I do to
fix or workaround the problem?

Are using KMDF in your driver or are you writing your own WDM driver?
