Speak directly to a PCI device without a driver?

Question

I have a friend who has a PCI device that has no driver. Is there a command that will allow me to speak to this device without a driver? (we are trying to reverse engineer its protocols.)

I will basically be fuzzing it with random data.

The command setpci might be what you're looking for.

You can check if its getting detected by the OS. run the below command

#lspci -----> check the output and see if you can get the attached PCI device

I don't want to find the device, I want to communicate with it. How might I do that? – MrSynAckSter Feb 12 '15 at 20:42
Without the exact device Module, it will not communicate as you want. – AReddy Feb 14 '15 at 18:08
Surely there is a way to pipe directly to an unknown device at a known location. This device has no driver – MrSynAckSter Feb 14 '15 at 19:37
