Usb Hub
Is it necesary to connect the AC power adapter to a USB hub?
I just bought a USB hub (Belkin), it includes a AC power adapter to plug it to the wall. The user guides ask to connect the AC power adapter to the USB hub.
But I've found that USB hub works well without having to connect the AC power adapter.
Is it necesary? What might happen if I don't use it?
The power supply is to help provide a boost. If you had certain external hard drives connected they may need that additional power to help them operate correctly. Nothing will happen if you don't use it but if you have a lot of things connected and speeds slow down, give it a try.
