    hmm, i dindt know that... i thought if it output of amperage is 4amp it will supply 4amps even if not needed

    so basically what i said in last post, to take 12volt line and drop it to 5volt is a waste of time.

    I will go now and tap it into the 5volt line


    Thanks for the help, really appreciate it

    Okay before attempting something on this magnitutde, you are going to have to gain a better knowledge of electronics. Ohm's law would be a good start.

    If you hooked it to the 12v+ line, the hub is garbage. Unless you know how to SMD solder, there is no hope of recovering it.

    Voltage doesn't drop with less amperage drop, and vise versa. If a device is designed to run on a given voltge, it is going to pull upto a certain amount of amperage.

    Well you stated that smoke was coming out of the hub....

    smoke usually indicates that you have "fried" a component, no?

    But if it is showing your DVD drive hooked up to it then it must be working. Windows must not be detecting your mouse for some reason. It could be a driver issue (esp. if you've done an Nlite install or similar). Try putting your mouse in a different port and see what happens.
