The DUB-H4 is a common model for sale in many countries. It sports a total of four ports and is listed as being USB 1.1 compatible - only, however, by virtue of one single transaction translator.
There are many situations in which you may prefer to use the hub without any power: when traveling, or when you don't have to time plug it into the wall socket. Unfortunately, the D-Link website doesn't say how much power the hub puts out in those circumstances. If you use the adapter that comes with the hub, it will produce 500 mA per port.
It measures a fairly compact 10x6x2.5 cm. We were pleased to see that the uplink port to the USB controller was implemented with a standard cable - proprietary solutions tend to be more common. Nor shall we ignore the length of the connecting cable: 1.5 meters. That's long enough to hook the hub up to not just a laptop, but also to the tower PC hulking under your desk.
