Whoops. I just noticed that I missed out on a huge bit of my log on the 
"switching" of USB ports. Here's the log:

It kept on switching from ttyUSB0 and ttyUSB1 to ttyUSB2 and ttyUSB3 
(notice the last few addresses 21 and 22). Strange though, as I just 
tried it again, and it consistently connected at ttyUSB1. Will have to 
monitor this further, but for now it works!

Maybe I just needed sleep at 3:48am...
