Is there a way that I can always have it show up as /dev/ttyUSB0
I think the proper way is to provide a udev rule to identify the
device and assign a fixed name to it.

The other option is to write your software so that it gets notified
when a USB device is installed/removed. You will be told the actual
device name. I needed to do this to detect insertion/removal of a
barcode reader.
Looking at the actual code it is setting a default value of /dev/ttyUSB0.
It should not be defaulting when you try to set it in the call but it
may be interesting to set the default to /dev/null so that it will not
do something that may be reasonable part of the time.
When you say that you cannot get anything but /dev/ttyUSB0 to work it
makes me ask is there a problem that is causing the default to always be
taken.
Forcibly breaking things can be a useful tool.
