These things can certainly cause a few headaches at first!!!!
Strange that you're having power issues like that - I've had no issues plugging three of them at a time into my PC's front USB 2 and 3 ports. (Asus P8Z68-V mobo and a Fractal Design R4 case)
I've also had no issues running five of them at once on a powered D-Link hub with a 4a power supply... Maybe check the rating on your hub's power supply.

I'd advise strongly against using cgminer... The driver support is horrible!
I'm using BFG at the moment and have a batch file set up to start mining when the PC is turned on - no intervention needed, it just works!!!
