How can i read futaba sbus signal(serial bus) through usb adapter

edit

Hi there I have a ongoing project regarding an indoor autonomous drone. My idea was to use a rp lidar to sense the surrounding and obstacles given. The transmitter's receiver will be connected a USB adapter to a NUC through ROS, this is to allow me to edit the sbus signal to the flight controller. However the problem i faced right now is that the signal from the receiver shown in the ROS is gabled.

The result shown is attached below.

papapa@papapa-desktop:~/catkin_ws$ ls /dev/ttyUSB*
/dev/ttyUSB0
papapa@papapa-desktop:~/catkin_ws$ rosrun serial serial_example /dev/ttyUSB0 115200
