I purchased an 8bg fuze two days ago.
I came home opened the package, connected the unit to my Dell E1505 (Win7) and it was immediately recognized and some sanza application came up. I was suprised to see it since had not installed anything related to the sansa on my computer. I closed the application. I let it charge for a while, then disconnected it, turned it on and it worked well.
I then took it to my desktop PC where I have all of my music, and connected it. I got a message “USB Device Not Recognized” My desktop PC has Win Vista so I thought maybe it was a driver issue. I inserted the cd that came with the sanza thinking maybe there was a driver on it, but nothing useful was on the disk.
I disconnected the cable from my desktop PC and reattached it to my laptop, and now I get the same message “USB Device Not Recognized”
I tried the following:
pushing the power switch up for several seconds while connected to the PC. After a few seconds it went black. I powered it back on and same message.
restoring the factory settings same message
changing the USB connect mode, powering down both the pc and the sansa the reconnecting three time for each setting and same message
connecting to every usb port on both my desktop and laptop pc same message
manually install every type of legacy mtp device one at a time, rebooting same message each time
