I do not believe this was caused by the anything the OP did. Even if the OP did mis-install the front panel USB connectors (Which is difficult to do because of the locating pin allowing the connector to only be installed one way), USB ports should have current limiting and fault protection on them so too much current can't go through to cause any damage.

In my past experience I've seen components on motherboards release their magic smoke for absolutely no apparent reason. Just a defective part or manufacturing defect.

No one has asked the OP if the computer was even running OK for a time period before the damage occured, and if he was even using the USB port when it happened.
