Interrupt Request XX not available

NTDEV
1

Hi All:
I’m now writing a usb HCD driver.
when the driver does not startup, the resources (Memory Range, and Interrupt Request) allocated for this device is not conflict. But after I installed my driver, the interrupt request becomes not available. I process the IRP IRP_MN_QUERY_INTERFACE by simply deliver it to PCI bus, is this can lead the interrupt unavailable?? or something other is go wrong ???

Best Regards

What exactly do you mean by “the interrupt request becomes not
available”? And how are you attempting to connect to the interrupt for
this device?
