Hi,
I have a problem with interrupt. It works when Checked version is running (with DebuPrint),
and does not work when Free version of my driver is running.
Could someone help me in my case?
Thank you.
What kind of interrupt (usb or a hardware interrupt)? What kind of
problem? A bugcheck? An interrupt storm? The more details you provide,
the more help you can get.

Hi Doron,
Thank you for your respond. I have hardware interrupt and it works correct when I run Checked driver version,
but ISR is not called when I run Free version. In first case I use DebugPrint.

Yes, IoConnectedInterrupt is called from MyStartDevice, not MyDIspatchPnp.
KeSynchronizeExecution( dInfo->InterruptObject, EnableChipInterrupt, dInfo ) function enables the interrupt in hw.

Where did you get the DebugPrint macro? Note that, in most cases, such
a macro does not print anything in a free build. If you are using the
lack of debug output to conclude that the interrupt aren’t happening,
then you have fooled yourself.
You still haven’t shown us the ISR.
