Possible to Damage a Motherboard from Improper Front Panel USB?

Currently I'm dealing with a two-fold problem caused by an improper front panel USB connection (reverse-polarity).

The first and most immediate issue was the potential loss of 2 external hard drives (presently waiting on a universal drive adapter), documented here:

During this research I came across speculation that any kind of USB device that utilizes an external power supply (such as the external hard drives) *might* pose a threat to the motherboard itself :o  . I suspect this might be due to the reverse polarity presenting an input electrical charge into the system.

My basic question is if anyone is aware of such a thing. In other words, would it be safe to simply install the front USB port correctly and go about my business? Thanks.

I should also add that when the two external hard drives were plugged into the system there seemed to be no aberrant behavior (e.g., pops, clicks, sparks, smoke).

The only way to find out if something broke is to try it and see. If you didn't see any signs of distress, you might have gotten lucky.
