Like I said the one I got was from a company called WindmillTrading.com. It sure solved my MJ power problems, after I wasted money trying a few other powered hubs. Apparently the trick is that this hub has a whopping 2200mA power supply. I'm no computer expert but that's what worked for me! They even have on their site that their hub will solve MagicJack poewr problems... and as far as I'm concerned they're right!
I looked up the link again:

Hope this helps.
Good find "CheapGuyNo1",
But they are not doing anything special, they are just living up to the specs for a four port Powered Hub. The specs are .5 amps per port, which this hub meets. The problem with these other manufacturers is they are just boldface lying about their hubs meeting the "Powered Hub" specifications.
For $19 dollars I may just pick one up for ... well I don't know but at that price I wouldn't mind leaving it on the shelf for some impromptu emergency.
