D435 - USB SCP overflow,1.55236e+12,Error,Hardware Error

[jdwolk]

Device: Raspberry Pi 3 Model B
OS version: Ubuntu MATE 16.04
Camera: D435 (over USB2)
Firmware: 5.11.1.100
librealsense version: 2.18.1 (unpatched, for USB2 support)
ROS realsense version: 2.2.0
ROS version: kinetic

Hi!

When I run roslaunch realsense2_camera rs_camera.launch filters:=pointcloud I get lots of warnings that say the following:

[ WARN] [1552356094.393717336, 194.518000000]: Hardware Notification:USB SCP overlfow,1.55236e+12,Error,Hardware Error

I get topics showing up in rqt but no Pointcloud2 data seems to be appearing in rviz on the /camera/depth_registered/points as expected.

Also, librealsense seems to be working ok as realsense-viewer, rc-depth, etc, are working.

Thanks in advance for any help!

I was able to find a workaround with the following:

roslaunch realsense2_camera rs_camera.launch filters:=pointcloud enable_infra1:=false enable_infra2:=false

My guess is I was getting the USB SCP overlfow error because too much data was being transferred over USB 2. By disabling infrared I think I took some of the pressure off so now no overflow 🤷‍♂️

Still seeing the same thing when I try running higher resolutions and framerates on Odroid XU4 over USB3

@jdwolk Could you please provide more details about the higher resolution and FPS you tried? As you're using USB2, the bandwidth is limited which compared with USB3. If possible, you can have a try with USB3 for higher resolution and FPS. Thanks!

@chenbo1173 Did you also see this issue Raspberry Pi 3? If so, then as told in previous comment, the bandwidth of USB2 is limited which compared with USB3. The default launch files enable depth/IR1/IR2/RGB streamings which is very stress for USB2 connection case. Please disable some streaming to try again and share your result. Thanks!

I'm having the same issue, and it prevents me from using the AR_Marker utility properly.

I'm having the same issue on a USB3 port, any resolution?

Same issues running on Rpi 4 on USB 3 (!!!) connector:

[WARN] [1613385028.678995219] [RealSenseCameraNode]: Hardware Notification:USB SCP overflow,1.61339e+12,Error,Hardware Error

when running:
ros2 launch realsense2_camera rs_launch.py enable_pointcloud:=true device_type:=d435

after installing Foxy Version but replacing Step 2 with this installation.

@QuarTerll @MarcoDotIO @andresgalaviz @patrickw135 Please type "lsusb -t" to check USB connection is really recognized as USB3. Sometimes the connection will be recognized as USB2 if you use USB2 cable.

I have the same issue,I have modify and rebuild the code. when this occur, do the hardware reset, this problem can be fixed.

FYI: I use the usb2.1;

I had similar issues, after hardware reset and firmware update via realsense-viewer, the errors are gone.
