In the middle case, there are “short cable” hubs which typically use an integral 6-inch cable to slightly distance a small hub away from physical port congestion and of course increase the number of available ports. So no green light when you plug in a USB flash drive or mouse? Laptop computers may be equipped with many USB ports, but an external USB hub can consolidate several everyday devices like a mouse and a printer into a single hub to enable one-step attachment and removal of all the devices. Consequently, plugging a device into one port may physically block an adjacent port, particularly when the plug is not part of a cable but is integral to a device such as a USB flash drive. Only the simpler switches tend to be automatic, and this feature generally places them at a higher price point too. It may be desirable to use a bus-powered hub with self-powered external hard-disk units, as they may not go into sleep mode immediately upon computer shut-down or sleep mode when using a self-powered hub since they will continue to see a power source on the USB ports when using a self-powered hub.

For example, many seven port hubs have a 1A power supply, when in fact seven ports could draw a maximum of 7 x 0. Active cables specialized connector-embedded one-port hubs perform the same function, but since they are strictly bus-powered, externally powered non-bus-powered USB hubs would likely be required for some of the segments.

I’ve upgraded from Windows XP to Windows 7. VanessaET Created on Mtr 14, A bus-powered hub passive hub is a hub that mrt all its power from the host computer’s USB interface.

Please update this article to reflect recent events or newly available information. Laptop computers may be equipped with many USB ports, but an external USB hub can consolidate several everyday devices like a mouse and a printer into a single hub to enable one-step attachment and removal of all the devices.
