Different devices take different amounts of power to charge. The Fuze seems to be hungry. So neither the hub nor the 600ma standalone charger will do the job, or will take forever.
Here’s a post suggesting that 800ma will work

And if you get a 1.0 amp, you should definitely be rockin’.

Just out of curiosity, can you charge your cell phone from either of those sources? They are pretty greedy too.
As for tags, the Fuze was really made to work with Windows-style tags. (ID3v2.3 ISO-8859-1). The Unicode (UTF) tags used by the Mac can sometimes make trouble. And if you are using MACOSX, the Mac finder files (something like ._01.songtitle1.mp3 and 0kb in size) have the Fuze trying to read them as songs because of the mp3 extension.
There’s a Mac program called Dot Clean that will take the finder files off the Fuze for you.

See if you can find a Mac tagging program that will write ID3v2.3 ISO-8859-1 tags. Windows users have mp3tag but in Steve Jobs’ walled garden, you’ll probably have to find something else. It is a good idea to clean up the tags.
