I have learned to leave stuff plugged into USB sockets i possible they seem very delicate,a good idea would be to standardize the plug from the front panel to the mother board usb socket so they could be changed,the front one on my newish case went TU but I had a couple of older cases that I removed the small front panel and connectors with the idea of replacing the buggad one both had different connectors on em that did not fit the pins on the MB.

Did eventually find a old case in the back lane on bin day and plundered it,front panel USB socket replaced and ok now,waste not want not.
