Hello Sir,

i hope you will understand what i want to say :)

Hello
It may be the case that there is not enough USB bandwidth to handle all 3 cameras.
If you plug just one camera, does it work properly? If yes, then add the second camera. If two cameras do not work properly together, try switching the second camera to other USB ports. When (and if) you find working ports combination for 2 cameras, then try to extend to 3 cameras.
