I've spent hours searching for a power supply to buy to power a USB hub, and the only thing that I have found is a cheap plug-in converter for car use that puts out 500ma. For a 4 port USB hub you need 2 amps, if the downstream devices are not self powered. Since USB devices are all 5vdc, self powered devices would pose the same problem.
The Carnetix people make a nice little 3 amp 5 vdc unit that fits into their P1900 DC-DC converter. And if you Google 12 vdc to 5 vdc converter you'll get a raft of results. Allied Radio (http://www.alliedelec.com/) has a range of these but they're pretty pricey.
