| Adding a USB Hub? Get More Power! |
|
|
If you decide to add a USB hub to your configuration to give you easier access or more ports, a powered hub is a better choice than a passive hub. A powered hub has to be plugged in separately to AC power, but it also allows the use of nearly any kind of USB device. Passive hubs, which are powered by the computer via the USB port, sometimes cannot pull enough juice to operate certain kinds of USB devices, such as cameras or even phone chargers.
