StreamClassInitialize failing


When I try to install my stream class driver that I developed in Windows
2000 (Debug Mode) I get the following message:
“StreamClassInitialize: Unable to find interrupt for the device”
in the debug output and the system goes into exception. Now, If I hit the go
button on the Debugger the system proceeds fine. The problem is that When I
try to do the same in non-debug version of the windows the system crashes.
This happens only during the install time and the system is able to boot
normally on the subsequent boots. I searched for the function
“StreamClassInitialize” but could not find any documentation neither in
Windows DDK nor on the Web.
Can anybody throw some light on this.
