Missing or dropped frames, mysterious camera connection problems, here is the solution!

[kheki4]

For your information, we had a strange problem: that sometimes frames got "dropped" or missed, so to say. It could be perfectly seen in Pylon Viewer. PupilEXT just showed a blank white screen, or quitted without no error message. In Pylon Viever, we could see that sometimes even the connection was lost with the device, but we did not understand why. Even changing different (passive, 1.5 metres long) USB3 cables did not affect the problem. But finally, we found a special USB3 cable with additional power supply (active cable), and that solved the problem! :)
