USB power has nothing to do with the OS. It depends on the device itself. Some hubs are self powered, in which case they get their power from the system; others require more power, and those have their own power supply.
A bus-powered hub is a hub that draws all its power from the host computer's USB interface. It does not need a separate power connection. However, many devices require more power than this method can provide, and will not work in this type of hub.
Under Linux, you can use hwinfo --usb or for more detail try lsusb -v -t if hwinfo --usb is not installed you can install it.
Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command below.
sudo aptitude install hwinfo usbutils
Some self-powered hubs do not supply enough power to drive a 500mA
load on every port. For example, many seven port hubs have a 1A power
supply, when in fact seven ports could draw a maximum of 7 x 0.5 =
3.5A, plus power for the hub itself. Designers assume the user will most likely connect many low power devices and only one or two
requiring a full 500mA. On the other hand, the packaging for some
self-powered hubs states explicitly how many of the ports ports can
drive a 500 mA full load at once. For example the packaging on a 7
port hub might claim to support a maximum of 4 full load devices ".
So I would check with D-Link.
Most portable media devices sync data to a desktop or laptop computer
via the USB port. The batteries in these devices can also be charged
by that same powered USB connection. There may be situations, however,
when you may need to change the default power settings of a particular
USB port so the device connected to it does not interfere with the
your computer's performance. For example, some types of devices
connected to a computer's USB port can prevent the computer from going
into its power-saving "sleep" mode. In Ubuntu Linux, there is a way to
modify the power settings for the USB ports.1
