Shuts Down when connected to PC

My Fuze+ was working great, then stopped being recognized by PC.  I followed the tips to solve that problem, but no luck.  I was able to connect my old Fuze and put stuff on there, and use the SD card on the Fuze+.  It plays, it charges when plugged in to the wall or car outlet, but shuts down when connected to any computer.

I formatted it.  I restored to factory settings, I followed all of the online Regedit options and still nothing.  Anyone else have this problem?
