No device found on Ubuntu16.04

I am a new beginner of astra sensor.
I have bought a device orbbec astra and I could not connect to the device.

this is my ‘lsusb’ result :slight_smile:

this is my [[rosrun astra_camera astra_camera_node]] result :

_No matching device found… waiting for devices. Reason: std::_cxx11::string astra_wrapper::AstraDriver::resolveDeviceURI(const string&) @ /home/ijpark/catkin_ws/src/ros_astra_camera/src/astra_driver.cpp @ 632 : Invalid device number 1, there are 0 devices connected.

The projector of the sensor is always on when i plug the usb cable to the computer.
I think that is strange because usually the projector only turns on when i run the application to adquire images.

Can anyone help me with this issue?
