Query: Pretty, but pretty useless as well

I purchased one of these for my HP DV-1000 laptop, which was notes to have "some reduced functionality" when I purchased it. It should have been written "almost no funtionality." Practically none of my peripherals work in the expansion USB ports, except for one thing (Hauppauge WinTV-HVR950), which isn't supposed to work with a USB expansion dock, but it works just fine. Other things (printer, scanner, digital camera, et.al.) refuse to work.I had a spare power brick from another computer that gave up the ghost, so I didn't have to shell out for a spare one, but most people will either have to come up with another $50 for a spare or lug their power supply with them if they want to use their laptop away from the docking station.I wouldn't buy it again.
