Has anyone experience of using the above driver?

I have successfully build and installed the driver on my system, and
installed the atmel-firmware files.

Despite this, whenever I try to load the driver I get an error saying
that the driver failed to find at76c503-rfmd-acc.bin despite this file
now being littered around my system as I try to guess where the driver
is hoping to find it!

Any suggestions are welcome as this is becoming very frustrating!
