Thanks mate I was originally just testing them to make sure that they worked since they were used but I figured that it was the power consumption that was happening making it not work properly and after a little google searching I came to the same conclusion that you did and already ordered myself a good industrial hub last night Thanks so much for helping me out though Cheers
The Dipo 19 or 10 port hub would be a good choice. They come with their own power supplies (110-240V) and all the cables you need so are ready to use out of the box. 10 port hub comes with wall mounts too.
