MY POST SHARED HERE:
Out of nowhere, my Sansa fuze was not being fully recognized by my computer. I tried a number of the suggestions on this topic thread and found a solution of my own. I haven’t read every post but I’ll tell you what worked for me.
Plug the Sansa Fuze into a USB port
R-CLICK My Computer
choose properties and then the Device Manager
Under PORTABLE DEVICES I could see my Sana Fuze with a little yellow triangle in it
R-CLICK on the triangle and choose uninstall driver
Disconnect the Sansa Fuze then reconnect it and it’s like you connected it for the very first time. The computer searches for the proper driver and VOILA my Sansa Fuze was recognized again as if nothing ever happened.
I hope this helps some of you. OBVIOUSLY, somehow, the USB driver for the Sansa Fuze became corrupted. This worked for me. I hope it helps you as well
Good Fortune to you!!
