As a quick clarification; I did make one change to the code. I changed the
code to connect on /dev/ttyUSB0 which it appears to do successfully when I
launch the package.

Might I need to change the baud rate in Ubuntu? E.g., "stty -F /dev/ttyUSB0
speed 57600" ... or something more complete like "stty -F /dev/ttyS0 57600 raw
-parenb -parodd cs8 -hupcl -cstopb clocal"
I'm away from my Create at the moment, but I'll try this later this evening if
I don't hear otherwise before then.

I see that
http://brown-ros-pkg.googlecode.com/svn/tags/brown-ros-pkg/irobot_create_2_1/bin
/irobot/create.py already sets the baud to 57600 and along with the other
serial connection settings. Do you have any other ideas for the behavior that
I'm seeing?

Sorry you're having trouble. A few questions that might help us sort everything
out:
1) What version of ROS are you using? There were a number of new versions
released in the last couple of days and we haven't had a chance to test them
all so far.
2) Does your Create play a song when you start up the driver node?
3) Have you tried using our stock driver and using:
rosparam set /brown/irobot_create_2_1/port "/dev/ttyUSB0"
to change the port instead of changing the code itself?
4) What kind of result do you get when you try attaching a serial terminal
(e.g. minicom) to the robot when ROS isn't running.
You're right about the baud rate being set by the driver, so I don't suspect
that's the problem. It does seem like a connectivity issue though.

Thanks for the quick response! I *think* the problem is my RS232-to-USB
adapter...I've verified that I'm also having problems connecting to my SICK via
the same cable. Will try my docking station which has a native COM port and
let you know how that goes.

Sure enough, it was the RS232-USB adapter cable. I got a replacement this
morning and it works like a champ. I'm very impressed by your Create node; I
especially appreciate the fact that only has a single non-ROS
dependency...great work!
