I am looking at the example I've chosen, cy_pci.c, and the pci code
figures out what to probe via linker sets, but I don't see the line in
your code below that corresponds to the line 62 of cy_pci.c, as I show
below:
DATA_SET(pcidevice_set, cy_device);
I think maybe you might be missing this line, so the pci code never
probes your device. If I'm wrong, I'll be watching with interest for
someone to correct me.
