MyriadX USB stick not working with USBIP

We are trying to interface The Neural Compute Stick 2 . The NCS2 is attached on PC1(running Ubuntu 18.04) and the device is accecced on PC2 (Ubuntu 18.04) via USB-IP, but it fails during test.

the USBIP attach is OK and I can see the USB device through lsusb.

Here is the output I have during the test:


root:~# usbip attach -r 192.168.70.104 -b 1-6

 Hi Sami,

 

Thank you for reaching out to us. We are currently investigating this issue and will get back to you soon. If possible, could you share additional information regarding:

  • CPU devices used to run this demo
  • OpenVINO version used on the system


Regards,

Adli

Hi, 

Please find the response below: 

1) We ran the demo on i.MX8

2)  Openvino Build ac65ea30fd90ec04bcf9a3c326f846d8f86f516d

 

I also tried the MyriadX directly plugged into the Ubuntu 18.04 Linux machine and ran the demo_security_barrier_camera demo.

The demo ran successfully.

But I found that the USB device is disconnecting and connecting two times even on the Linux machine.

Below is the dmesg log:

We found that this USB re-enumeration is the root cause of disconnect in the USBIP. If the device is not stable on the host side then the USBIP client-server connection also disconnects.  Is there any workaround or fix to avoid this USB re-enumeration while the demo is running?

Hi Sami,

 

Sorry for the delay. I don't think it is possible to avoid such USB re-enumeration as you mentioned in the latest reply. This occurs by design and cannot be changed. Therefore, the USBIP usage would be unworkable due to this NCS2 behavior.

Adli

Hi Sami,


This thread will no longer be monitored since we have provided a solution. If you need any additional information from Intel, please submit a new question.
