Interrupt resource conflict

WINDBG
1

Hi folks,

Seeing this issue on driver installation ?

This device cannot find enough free resources that it can use. (Code 12)
CM_PROB_NORMAL_CONFLICT.

Any ideas how to figure out what devices/resources would be causing the
conflict?

my windows image does not have the troubleshooting.

Thanks,

Harshada

You’ve connected WinDBg, set breakpoints in your code where you get your resources? Stepped into AddDevice? Stepped in processing of the START IRP? Given it’s your driver, I’d be willing to guess that it’s your driver causing the conflict.

From the debugger, you can use !arbiter to see conflicting resources (see
the docs for how to interpret the output).

Windows\inf\setupapi.dev.log can give you some clues.

i used !arbiter 4 since i am seeing conflict with interrupt resource. But the list i get doesn’t list the the driver which did not load due to the conflict.

I wouldn’t expect it to show the function driver that didn’t load, that’s
not the purpose. What it should show is the resource in conflict and the
PDOs that are trying to claim it. This will let you see the device that
currently owns the resource you’re trying to claim.
