It's just yours. My computer has been through sleep, reboot, and shutdown with it still plugged, and still works fine after computer is on again.
What you're describing is actually a pretty big problem, and if this was in all the FC660C, there would be a lot of complaints by now. Try a different computer to see if it has the same problem. It might be how your mobo handles USB devices, or some weird driver/software installed on your computer.
