That's -ENOENT, which means that userspace wrote a zero-length file
or told request_firmware to return with an error.  It doesn't necessarily
actually mean the file couldn't be found.

When I say "userspace", what I mean is /lib/udev/firmware.agent.  It writes
its errors to syslog.  Do you see anything there?

Thanks for reporting and sorry for the slow response,
Jonathan
