i had this problem with my ipod, and still sometimes do have it. it could be
that one of your usb points doesnt work properly...

ive also just recently completely wiped my computer and am now starting from
scratch as there was too much crap on it that was causing things not to
work...

if your still getting the same message, so print screen copies of the
mesages coming up and bring them in with you if you return this one... i did
this and it means that they cant question what is going wrong as there is
there is the proof... my friend had problems with his ipod and when it was
sent to apple to fix it apply tested it and said nothing was wrong...
