We are trying to interface The Neural Compute Stick 2 (a USB stick from
Intel) with I.MX8, but it fails during test.

This device hosts a MyriadX which is a co-processor for neural network
acceleration.

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

Here is the output I have during the test:

root@imx8mqevk:~# ./security_barrier_camera_demo -d MYRIAD -d_va MYRIAD
-d_lpr MYRIAD -i car_1.bmp -m
./vehicle-license-plate-detection-barrier-0106.xml -m_lpr
./license-plate-recognition-barrier-0001.xml -m_va
./vehicle-attributes-recognition-barrier-0039.xml

After that, the device is no more visible on lsusb.
