iCrest 2 (Xavier NX) with M300

Hi there,

I got the following error on running roslaunch dji_osdk_ros dji_vehicle_node.launch

NODES

Setup

iCrest 2 (Xavier NX)
M300
OSDK 4.10

PARAMETERS
 * /rosdistro: melodic
 * /rosversion: 1.14.13
 * /vehicle_node/acm_name: /dev/ttyACM0
 * /vehicle_node/align_time: False
 * /vehicle_node/app_id: *********
 * /vehicle_node/app_version: 1
 * /vehicle_node/baud_rate: 1000000
 * /vehicle_node/enc_key: *************
 * /vehicle_node/serial_name: /dev/ttyTHS1
 * /vehicle_node/use_broadcast: False

I tried to solve it by adding DJIDecices.rules file into /etc/udev/rules.d, but it still gave me the same error.

I checked usb connection via ls -l /dev | grep ttyACM*, and it gave me the following: crw-rw---- 1 root dialout 166, 0 May 2 10:49 ttyACM0

iCrest 2 has already been integrated with dual USB cable as shown below. So, I think the hardware and connection is OK.

I strongly appreciate any help in advance.
