I just discovered when I pluged my Nano to my PC that it is not working. USB Root Hub "Unknown Device"
"One o the USB devices attached to this computer has malfunctioned, and Windows does not recognized it" I tried it on a different PC, the result is the same. Thank you in advance.

ITunes is installed. I tried to reset, but nothing working. I brought it over a year ago. Any suggestions?
Go to My PC,Properties, Hardware, Device Manager and delete everything it has to do with USB, then select the computer from the menu Action, find hardware changes.
Also try using a powered HUB or try to connect with the battery on the Ipod full.
