Blackfly S BFS-U3-27S5M error [-1011] after camera is booted up, ok after

We have a Blackfly S BFS-U3-27S5M here, Firmware version 1910.0.365.0.

Using the Python SDK and this very minimal program:

```

import PySpin

pyspin_instance = PySpin.System.GetInstance()
cameras = pyspin_instance.GetCameras()

for cam in cameras:
    cam.Init()
```

We always end up with error [-1011] for the first try after the camera was (re-)connected. But it works without problems after that until next re-connect of the camera. It was correctly recognized as USB device before, though.

The same error also appears when using SpinView:

Where should we look for a solution? Could it be the firmware?

  Hello Christoph, 

  I don't think I have heard of such a problem before.
  You are already using the latest firmware.
  Has the camera worked fine before? 
  Which Spinnaker version do you use? How do you power the camera? 
  Do you have another PC you could test the camera on to see if you see the same issue there? 
  
  Best regards,

  Manuel

  Hej Manuel,

  I think the camera once behaved better. But we switched to Windows IoT, so who knows ... I tested on a Linux computer using SpinView, and had no problems whatsoever.

  I'v now fallen back to a dirty hack of always initializing and de-initializing it in a try-catch, and then initializing it. That works for now, of course :-)

  Hello Christoph, 

  If you want to take a closer look at this, you can also open a support ticket on https://flir.custhelp.com/app/ask 

  Then we can also do a remote session to look at the system together. 
  
  Best regards,

  Manuel
