    I don't think that it will be possible to repair the devices plugged into the hub at the time. You probably fried the internal components already. Sorry.

    Once you let the smoke out of the little cans it's almost impossible to cram it back in.

    All the noobs say no, because they have not done such an operation.

    Yes you can fix this problem. You supplied more than the designed current to the USB hub. The USB hub is a very easy to replace part of the system board. It is usually a 16 pin (4x4) chip which can be bought from Mouser Electronics/Digikey/Goldmine Electronics for less than $5

    You will need to open your laptop and locate the USB controller. Look for the numbers on there, and look up that number in any of the electronic stores mentioned above. If you cannot find it post up some good quality images of your motherboard and I can show you where it is located.

    You will need solder, solder braid/a solder sucker, and a soldering iron to remove/reinstall a replacement USB hub.

    The process does take some time, but it is well worth it in the end, as you do not need to replace the laptop.

    I think the OP is talking about an external powered USB hub, not the USB ports on his laptop - he fried the peripherals plugged into the hub.

    I would say that given the low prices of USB hubs these days, it's not worth your time to isolate the problem and fix it, which could get messy and take a lot of time.
