Solved the error by using a USB hub -_-||. But met another error that is when running an demo, terminal shows

"dispatcherEventSend: 738 Write failed -1dispatcherEventReceive: 200 dispatcherEventReceive() Read failed -1"

@renhanchi Is this a USB 2 or USB 3 hub?

@Tome_at_Intel USB2 hub

I am having the same issue. I've tried it on 2 different laptops. The first laptop I had the NCS plugged into a USB 3 port on the laptop. On my second laptop I have it plugged into a 3.0 port on the docking station.

My next step is to try setting up my Pi 3B+ to see how that runs. Using the VM sure would make things convenient though.

@Juan Currently there are issues running the NCSDK within a VM. Other issues: https://ncsforum.movidius.com/discussion/919/ncsdk-2-05-not-working-in-virtualbox-5-2-with-ubuntu-16-04-04#latest

@Tome_at_Intel is there any update on this issue….as i'm also stuck here. I had to switch to NCSDK 2 as i needed to work with fifo's. Any update/help is appreciated

@abhinandan00 We're working on a release candidate at the moment. I'll make a post as soon as we have a software release that addresses the issue. I appreciate the community's patience and understanding. Thanks.
