Shown
here to the left is the USB2.0 High Speed Hub
connected to 3 USB devices. The devices were
a USB Optical Mouse, USB2.0
/ IEEE 1394 Firewire Enclosure and a USB
Serial Adapter. As you can see the green lights
indicate a complete USB Cable connection between
the USB Hub and the other USB devices. All were
powered through the USB Hub with exception of
the USB2.0
/ IEEE 1394 Firewire Enclosure, because this
was connected to a USB Hub, it had to use an
AC adapter for power but other functioned properly
through the USB Hub. The singular USB cable in
back of the USB Hub is coming from the laptop
that was used in testing that powered the USB
Hub.
NOTE: The fourth USB cable connection was left out to show
the difference between powered and non powered or empty
port connection. The red LED indicates power from the PC
or laptop via the USB cable. |

USB Hub Testimonial
This
is a pretty cool little box! What really surprised
me was how much it could handle. I had a USB2.0
/ Firewire 2.5 inch hard drive enclosure, USB
Optical Mouse, USB to Serial Adapter and although
you don't see it, I also used it to upload the
images on this site via the USB cable Connection
on the Hub. I actually had all 4 USB devices
connected at one time and all functioned perfectly
from copying files to the enclosed drive to using
the optical mouse to point and click on my applications.
The USB Hub functioned as though it was a USB
port on my laptop from recognizing the devices
as the were connected to the functionality. This
really is a great accessory to have to use multiple
USB devices for one PC or laptop, especially
if your system is only equipped with one or two
USB port to begin with.
This is a must have for a USB port limited system.
