USB Drive not recoginzed after 4.1 update

Hello All,
I’ve updated my aTV to the 4.1 update and have an issue where my external USB drive, which worked on the past update, is not recognized by the aTV anymore. I have also tried to use a regular 2GB USB Stick and it was not recognized either. Any suggestions to try before I do a complete restore? (I did do the official update before the 4.1 that was stated in the instructions).
Thanks for the help!

After updating the AppleTV software the Smart Installer will need to be re-ran.

That did it.
