I received this Hub here shortly but now I see it is very well designed. Tow of power and its connection long enough; It is easy to plug into the back: scan, printer, webcam ... on the front and removable: hard disk, key .... I who am running Windows XP I have no problems with recognition of this. The small indicator light helps ensure it works properly. I recommend this product still a bit expensive. At least that's the quality he still has 10 ports in this small box that fits easily under the screen.
