The file the device driver needs is an FPGA program file that - is data that I don't want compiled into the driver wasting space - will initially be specified when the driver is loaded via rc script - that can be reloaded by a program to customize it for a particular application I know that this isn't a a typical situation and I have only seen one other device driver like this. It is a 1553 driver that creates a /usr/lib/ directory for its configuration file.
