Xbox 360 Doesn't Recognize USB Plugged in

Hey all!

I have a 64gb Thumb drive that I use to play media from my PC onto my xbox, then onto my flat screen.

I removed the USB while the Xbox was powered off, to put more media on it, then I safely eject it and put it back into the xbox (while still powered off) then I power the machine in. Now when I open the system media player, I can't select portable device (it is not lit up it is just grey (an unselectable option)).

I have tried reformating the flash drive and deleting all data and copying it back over. Other flash drives are still recognized


My computerS still both recognize the flash drive though.
