Hi Nathan,

The tuner busy error code is ENODEV. It appears some devices aren't
created on your system. Would it be possible for you to send me your
config and a complete dmesg.

I am curious if /dev/media0 or /dev/media1 present on your system.
Not having this could explain the ENODEV you are seeing.

thanks,
