My USB appears to be connecting through ttyAMA0, that is why I am choosing that connection in Hyperion. I've tried the others as well and they fail also.
osmc@osmc:~$ dmesg | grep "tty"
[ 0.000272] console [tty0] enabled

I've tried other rates as well. Had no effect.
Yes. The rate in the sketch matches the config. I've test a few variants on this also.
The only thing at this point seems to be hardware related. I am thinking the video grabber might not be working properly, even though the launch indicates the grabber was started.
