there's certainly enough power for that. Theoretically you should be able to run around 12 LED's on one USB.
Buy a USB hub and connect to one of the USB ports. This splits any one USB port into 4 or 7 ports(depending on the model of hub).

try to run in safe mode... that's what i do...
A 4 x 4 electronic display should run on standard a 110v 15amp plug. The displays don't draw that much power as most them run on LEDs. It can vary by model. What you can do is but a meter. you plug the machine into the meter and it will tell yu how much energy the machine uses.
No, older USB devices do not run faster when connected to a new USB port. The speed of the device is determined by the device itself, not the port it is connected to.
Unfortunately not, if your port is USB 1.0, you can only run a USB drive that is 1.0 and you will have a very hard job finding one of those these days. You can run a 2.0 through a 1.1 port, but it will only perform at 1.1 speed.
it means it`s charging <plugged in via usb cable when PS3 is turned on or when using adaptor that uses wall socket>
Yes, you can run LEDs in Colorado. There's no regulation against them.
Yes. But it will run only at 1.1 speeds.
If your compairing apples to apples like 3 watt leds to 3w leds then 128. The more leds the higher the power.
Yes, LEDs run cooler than fluorescent lights because they convert more electrical energy into light instead of heat. This makes LEDs more energy-efficient and reduces the amount of heat they produce.
Yes, LEDs are dimmable.
