Hi, after running the launch file. There still exist some errors in the process:

[2148544.298]ERRORLOG/1 @ AdvancedSensing, L108: Failed to initialize USB Bulk Linker channel for liveview!
[2148544.298]ERRORLOG/1 @ AdvancedSensing, L115: Failed to create task for liveview!
[2148544.299]ERRORLOG/1 @ AdvancedSensing, L123: Failed to initialize USB Bulk Linker channel for perception!
[2148544.299]ERRORLOG/1 @ AdvancedSensing, L130: Failed to create task for advanced sensing!
[2148544.299]STATUS/1 @ AdvancedSensing, L135: Advanced Sensing init for the M300 drone
[2148544.299]STATUS/1 @ LiveViewImpl, L89: Finding if liveview stream is available now.

[2148545.099]STATUS/1 @ activate, L1329: version 0x3041202

 

Although these errors do not exist when i run as root user, but how can I resolve these errors even when not in root user mode.

  In terms of permission and access, this is what i have:

  $ ls -l /dev/ttyACM* && ls -l /dev/ttyUSB*
  crw-rw-rw- 1 root dialout 166, 0 Jun 21 10:06 /dev/ttyACM0
  crw-rw-rw- 1 root dialout 188, 0 Jun 21 10:06 /dev/ttyUSB0

  It is about how to add USB node with Ubuntu OS, if you can't add any file, please check the operation permission.
