Fuze not being recognized

Sorry, I should have listed that I use a USB wall charger and keep it plugged in about 75% of the time that I’m listening to it.  Battery is topped off. 

I have had other issues before about plugging it into one of my wall chargers (1 for home, 1 for work) and it going into ‘Connected’ mode.  It also happens on my Altec Lansing im510 speaker dock.  The odd thing is, it’s not consistently going into ‘Connected’ mode or just charging.  Half the time when I plug it into my speaker dock, it goes into ‘Connected’ mode and won’t play any music.  Same thing on my USB wall chargers. 

Another thing I noticed is that when I plug it into a computer, I do not get the battery charging ‘lightning bolt’ symbol over the battery.  One day the player was showing a half bar, so I plugged it into my computer and left it there for a few hours, came back and the battery bar hadn’t budged after I disconnected it.  Not sure if that’s related or not.

I bought this Fuze the day it came out at Best Buy.  I currently have firmware version V01.01.11A installed. I have tried removing the 4 GB microSDHC card I have.  Everything I do doesn’t work.  I think I’ll try 1 more ‘Format’ from the player later (hey… stranger things have happened…) and if that doesn’t do it, take it Best Buy and use my warranty plan yet again.  Big decision is if I decide to buy yet another Sandisk device, as I’m getting rather unhappy with the issues I’ve had to deal with since I got my few e200’s and upgraded to this hoping most of the issues have been resolved.

Thanks for the help.
