Driver PCI returned invalid ID for a child device

Hi Guys,
We have developed a PCIe based storage adapter and it’s driver. In some system we are seeing “Driver PCI returned invalid ID for a child device” in the Windows system even log. This occurs even if the driver is not loaded.

I was wondering what this error means and what can we do to solve this.

Appreciating your help.

Does the error show up if your device is not plugged in?

The error shows up only when my PCIe-based device plugged in ( with or without the driver loaded).

That’s because the error is about the hardware id reported for the device by the bus driver , not your driver.

Doron,
Could you please explain little bit more on that?
In what cases would bus driver complain about the HW ID? Is it format of the ID?
And why would bus driver not complain about this in a non-Dell system?

Thanks for your help

The ids are derived from data reported by your device. As to why dell only, I don’t know.

You probably want to have a look at PCI config space of your device (including the various capability structures), and see what you find… both on the DELL and non-DELL machines. See if you see anything different.
