13 years ago There are some conflicts with the new FTDI drivers, where FTDI devices show up as /dev/ttyUSB0, etc.
Try running:
sudo rmmod ftdi_sio
after plugging in the segway base.
ls -l /dev/ttyUSB* should yield no devices.
Try launching the segway node again.
The problem with this is that other devices that use the ttyUSB setup will not work.
It is a known issue by both IRI and wjwwood.
If that does not work, check permissions in /dev/bus/usb and be sure you can write to the segway device.

connect the RMP to the USB port (first to the base then to the computer). Turn the segway on, and start it in Tractor Mode.
then opened 2 terminal windows in one ran $ roscore
in the other terminal I ran: $ rosrun segway_rmp200 segway_rmp200
