How to configure 'segway_rmp' package with 'libsegwayrmp'?

[GDUT-BIRL]

I have got some 'CMake' errors when I make the 'segway_rmp' package in the catkin workspace.Actually,I have no ideas about the usage of the 'libsegwayrmp'.

@GDUT-BIRL Could you post some of the errors you received? Did you have ros--libsegwayrmp installed?

Hi,piyushk.I cloned the libsegwayrmp to my home folder and installed it by the way of the site --http://segwayrmp.github.com/libsegwayrmp/,but I got the error --Could not find a configuration file for package serial.--when I made the segway_rmp package.That means I have no serial package!So,I cloned the packge to my catkin_ws/src folder from https://github.com/wjwwood/serial.git and made it.I compiled the segway_rmp package again and it was OK!But,I got some erros again when I run the segway_node connected to segway RMP400:

Actually,I connect to Segway RMP400 with two USB cables.I trid to use the usb as the parameter of the funtion getParameters() in segway_node.cpp,but I always got the error --FT_DEVICE_NOT_FOUND--.
And I have ever successfully controlled the RMP400 with segway_rmp package configured with just libsegwayrp,that means no serial package and the errors about serial.But now,I have to reconfigure these packages because the PC was broken.

I received some infomation when I run the segwayrmp_gui(connected to RMP400 with two USB cables):

So,I guess I didn't install the driver successfully.
