Error - Could not open NCS device
What are you seeing?
User is unable to run the samples and see: Error - Could not open NCS device error.
How to fix it:
The Intel® Movidius™ Neural Compute SDK includes sample code for developers to run in these circumstances.
To resolve this, ensure the device is connected to your computer and is detected by Ubuntu* with the lsusb command.
$ lsusb | grep 03e7
Bus 003 Device 007: ID 03e7:2150
Bus 003 Device 007: ID 03e7:2150
$ lsusb | grep 03e7
Bus 003 Device 006: ID 03e7:2485
| Note | If the device is detected and the device ID is 03e7:2485 you are using the Intel® Neural Compute Stick 2 (Intel® NCS 2). The Intel® NCS 2 is not supported by the Intel® Movidius™ Neural Compute SDK, you will need to download and install the Intel® Distribution of OpenVINO™ toolkit. Take a look at the get started guide for the Intel® Neural Compute Stick 2. |
If the device is not detected by the lsusb command, check the following:
- Are you running Ubuntu* in a Virtual Machine?
- Take a look at the Installation and Configuration with a Virtual Machine Guide. Ensure the USB filters have been configured as described in the guide.
- Ensure any extension packs have been installed on the Guest and Host machine.
- Ensure the USB 3.0 controller has been enabled.
- Are you connecting the Intel® Movidius™ Neural Compute Stick to a USB hub or USB adapter?
- It is recommended to use a powered USB 3.0 Hub.
- Try connecting the Intel® Movidius™ Neural Compute Stick directly to a USB port on the computer.
