"USB Device not recognized

Well, sorry about the cord…is it still charging?

You could always  get a microSD adapter, connect that to the computer (or pop it into the slot for most current computers)  and load music onto the card, then stick the card in the slot. If it’s a card you haven’t already been using on the Fuze, Format it to FAT32 with Windows first.

If you have copies of your music elsewhere, you might also go nuclear. Take out any microSD card and go to Settings/System Settings/Format and format the Fuze. That erases all the content you’ve added, and sometimes it unscrambles the tiny little brain of the Fuze too. It’s a long shot, but it might fix the “not recognized” problem.
