Hi all, Here at work I have a Belkin 7 port USB hub. It comes with a power supply but at the moment I'm not using it and this does not seem to have affected connectivity or performance. I guess that this is because the two things I'm currently running off it, my PACmate and a Cannon scanner either have their own power supply or slave it from the PC. My question is, under what circumstances would I be likely to have to connect the power supply to the hub? Cheers now.
