When I run the demo program:
It works for less than a minutes and then I get the error:
RuntimeError: Communication exception - possible device error/misconfiguration. Original message 'Couldn't read data from stream: 'rgb' (X_LINK_ERROR)
Prior to running the program, if I run the lsusb comment, I see the "Bus 001 Device 003: ID 03e7:2485 Intel Movidius MyriadX" device.
After the error, I no longer see that device when I run lsusb.
If I try to run the program again, I get an error message that there are no available devices.
Only way to get it working again is to power cycle it.
