I have a fairly new hot-plug controller that I bought some time ago because it was cheap. it was just sitting around.
It is custom programming interface and needs a driver for Windows to use it.
Somebody designed this using a FPGA and gave it to me. It powers up.
Anyways, I decided to write a driver for it just for the fun of it so I can use it with windows 10.
It has M.2 and old OHCI controller (Is this USB 1.1?).
This is a very wierd combination
Upstream is old PCI so I need a system with a PCie to PCI bridge, I realize
Anyways, I am thinking I will need to write a bus driver that enumerates the PDO for the downstream devices as they are detected and plugged and presents them to Windows.
I would like to start off with KMDF model.
Is a bus driver good enough?. Or do I need to do anything else?.
