hmmm... i cant imagine why that would happen. what you want to do in times like this is trying basic hardware trouble shooting. the first thing you want to do is plug the mouse into a separate port on your computer and see if the mouse works then. if that doesnt work, it might mean that the mouse is not working properly, and the best way to check is to try using the mouse on a seperate computer and see if it works there. if the mouse works on a different computer, but not on any other port on your computer, i am not really sure what to tell you. however, i suggest trying out a flash drive in the affected usb port. if this works then it is the mouse.
these are just basic trouble shooting steps, and your problem could be a bit harder to trouble shoot. if you cannot pinpoint your problem through trial and error testing like stated above, taking apart your computer may be necessary, as the burning might have been the solder in your computer melting and burning your chips, in which case you will have to buy new parts to replace the parts you are missing...
