-517 is the error EPROBE_DEFER which is used when a driver can't get
it's resources (probably) due to a dependant driver not being
initialised yet. The device driver framework will retry later any driver
that returns that error value, so -517 errors may be normal for a system
and not true 'errors'. Of course, if the dependant driver is never
successfully loaded then it would be a true error.
