My computer cannot auto detect my Zen Micro after I updated the driver for my Zen Micro.
Even uninstalling all the creative softwares and reinstalling without the updated driver doesn't help.
Have you tried using different USB slots? My Zen isn't detected on my front ports (most other stuff is though, like PSP, Flash stick) but it is detected fine if i plug it into the main motherboard ones. Other than that, I haven't a clue!
