I use 9 biro longitech camera in NI VISION BUILDER AI. When i run the program, sometime it will hang and request-time out will be pop up just for camera 1 or camera 2 not all.How to solve it?

-Is this always occurs after same time and for same cameras?
-Do they work in NI MAX separately fine or they give same error?
-Did you try changing the cables and ports and PC and still same issue?
-Try unchecking the option "Allow the Computer to turn off this device to save power" under USB Connections in Device manager.

-And since you are using 9 cameras, please check you have sufficient memory(RAM) and do memory calculations.
-What is the resolution you are trying to capture at and which version of labview are you using?
