OK so far so good.. now we narrowing down the problem to the laptop.. I don't think that is the Hardware, but a DEAD Driver which hasn't been take care of.. with this I mean a USB driver or the second possibility is Windows ACTION CENTER got the hand on your Device..

Have you ever seen the Action Center coming up while you where connecting the iPod Nano? What did you do? Did you close it? May I be able to get some Picture so you can see what I mean I have several iPhone which are connecting to my computers. And it has happen last night that a TDK two week old USB stick wasn't recognized on my Windows Partition where I just used it a day before..it was blinking for say about 5 Second and then Jumping out... Since this Laptop is a MAC so and its dual Booting, I booted into the MAC. And surely the TDK USB was there shown and also Working..

Booted Back into Windows took another USB Stick and this showed up and worked instantly..

Now I disconnected that one and inserted the one which makes Problems.. then opened DEVICE MANAGER and there it was: Yellow Flagged.. The driver couldn't be loaded..

Removed the Failing Driver clicked on the Name of the Computer in Device Manager, Right clicked and SCAN FOR HARDWARE CHANGES. It brought the driver back again and also it was Yellow Flagged..

Took out the CDROM of the MAC Drivers for Windows inserted it and clicked on the Driver and selected Update Drivers.. within a few Seconds everything worked..

So look in Action Center what it is supposed to do when you connect your iPod Nano.. the bug will be there somehow..

Otherwise Remove all USB Drivers and then reinstall them in device Manager this will cure it..

Hope this helps

Have Fun
