Just bought 2 of these hubs and they are giving me lots of problems so far....what am i doing wrong?
Can you be more specific? What is the 5V rating of your PSU? My 25A can power 3 of these hubs. Calculate 0.6A per BE to be on the safe side, by the way.
Have you read through this:

@dentldir: I have 10 units of B1 (black models). Running 7 BEs on external ATX PSU power with no problems. Might be that C1's had some lower-grade electronics that starts getting burnt out...
