I’m stil not sure you have gotten exact directions about forcing a computer connection.
Leave the unit off.
Push the power switch Down to click into Hold position (orange dot in the slot).
Connect the USB cord end to the computer. Open Windows Explorer (Computer or My Computer).
Hold down the << side of the wheel. Connect the Fuze connector.
This should force the MSC connection. If you see Sansa Fuze in Windows Explorer, right-click on it and Format to FAT32.
And while you are connected, send over the latest firmware.
Your Fuze is either v1 or v2 hardware. If you know which one, download the correct version. If not download both.

UNZIP the file. You should see FuzeA.bin for v1, a differen .bin file for v2 (I have a v1).
Drag over the .bin file to the driveletter of Sansa Fuze. Disconnect and the firmware should install. If you have a firmware problem–and it certainly sounds like you do–this ought to fix it.
