I also see the backlight problem. I sent an email to mini-box customer
support and they indicated that a new version was coming out soon
that should fix it.
The messages are because the driver code from mini-box uses fprintf(stderr,)
statements for logging. This is different than the normal release code.
It should be possible to redirect stderr to /dev/null.
I haven't tried the IR either.
