ailed connection to device (1.2.4-ma2480) with error 5

[Kuse__Manohar]

Hi,

I have a Neural Compute Stick 2. I have an i7 with Ubuntu 16.04. I followed this: https://software.intel.com/en-us/articles/get-started-with-neural-compute-stick. I downloaded '2019 R1.1 ' which gave me the file: l_openvino_toolkit_p_2019.1.144.tgz

Everything went ok however, I am not able to run the squeezenet demo. I can confirm I set the udev rules correctly and my stick is connected to the PC.

```

$ ./demo_squeezenet_download_convert_run.sh -d MYRIAD

.

.

.

Run ./classification_sample -d MYRIAD -i /home/dji/intel/openvino/deployment_tools/demo/car.png -m /home/dji/openvino_models/ir/FP16//classification/squeezenet/1.1/caffe/squeezenet1.1.xml

However, as soon as i do -d CPU, the demo works. Some additional info

How can I fix this?

Hi Manohar,

Have you tried logging out of the system to ensure the usb dev rules are loaded properly? Also, are you connecting the Neural Compute Stick directly to your PC or a USB hub? Try to connect the NCS to another USB port. 

Regards,

Jesus

I am running ubuntu 18.04 and openvino_toolkit_p_2019.2.242 and feeling unhappy

Hi William,

OpenVINO is not officially supported on Ubuntu 18.04 (see supported OS here https://docs.openvinotoolkit.org/latest/_docs_install_guides_installing_openvino_linux.html) 

There is a workaround that was posted by a community member that might work, but this method has not been validated by Intel: https://software.intel.com/en-us/forums/computer-vision/topic/807156

Please let me know if you have any further questions.

Best Regards,

Sahira

I tried it on a Windows pc then back to 18.04
