SDK V2 issue using NCS on JOULE

Hello everyone!

 

I am currently using sdk v2, and running examples failed. I am using ubuntu 16.04 on Intel Joule.

 

I was getting the same error earlier, and suddenly it worked once, and started failing again.

 

I have installed everything based on the scripts given in the sdk. I have also tried installing openCV independently, but the same error persists.

 

vinay@joule:~/ncsdk-2.05.00.02/examples/apps/hello_ncs_py$ make run making run python3 hello_ncs.py; D: [ 0] ncDeviceCreate:307 ncDeviceCreate index 0 D: [ 0] ncDeviceCreate:307 ncDeviceCreate index 1 D: [ 0] ncDeviceOpen:501 File path /usr/local/lib/mvnc/MvNCAPI-ma2450.mvcmd I: [ 0] ncDeviceOpen:507 ncDeviceOpen() XLinkBootRemote returned success 0 W: [ 0] ncDeviceOpen:533 failed to find device Error - Could not open NCS device.

 

The device automatically disconnects after the blob gets generated.

 

Before running the program:

 

vinay@joule:~$ lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 8087:0a2b Intel Corp. Bus 001 Device 010: ID 413c:2110 Dell Computer Corp.

VL812 Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

 

After running the program

 

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 8087:0a2b Intel Corp. Bus 001 Device 010: ID 413c:2110 Dell Computer Corp.

VL812 Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

 

Any leads would be appreciated.

 

Thanks!

Does it work if connected to USB 2.0 HUB?

 

Intel Joule USB 3.0 Port -> USB 2.0 HUB -> Neural Compute Stick

@vinaych I also had issues with running the NCS with the Joule. I tried a powered USB 3 hub which didn't work for me. Afterwards I tried using a USB 2 hub which surprisingly worked, but unfortunately this solution did not work for other users. Make sure your firmware and Ubuntu for the Joule is up to date: https://software.intel.com/en-us/flashing-the-bios-on-joule https://software.intel.com/en-us/videos/installing-ubuntu-on-the-intel-joule-compute-module.

Thank you @Tome_at_Intel & @PINTO. Surprisingly it is working with a USB 2 Hub. But it doesn't work with USB 3 hub and also when plugged directly to joule. Not sure why.
