The BT seems to carry enough information. I can see it specifically identified on the log.. That's how I discovered Centos would close the USB connection and reconnect it on another port.
Looks like I have to delve into the finer points of UDEV. Has anyone used a Broadcast Tools SRC-4 to drive an input on the GPI-16. Having a devil of a time getting this combo to work.

They do that, unfortunately. If you do some Googling, you'll find out that there's a way to tell udev to assign a specific name to the device, such as /dev/btswitch, which you can use in RD regardless of whether it gets recognized as /dev/ttyUSB0 or /dev/ttyUSB1. That said, what worked in Debian 6 doesn't necessarily work in Debian 7 as udev keeps getting played with by the developers. Also, some USB-to-serial-port converters don't carry enough identifying information for udev to uniquely distinguish one from another. At WCRI, I lost patience with this nonsense and installed an old fashioned serial port card.
