My computer or iTunes wont detect my iPod when I connect it. What can I do to make it work?

Does your iPod show it's charging? Do you get a sound from your speakers signifying something is now connected? Did you try another USB port? Another Computer? Abit AN8 AMD64 X2 4200 @2.5Ghz Corsair 3Gig Dual-Channel 2x512 2x1gig MSI R4830 Seagate 160Gig SATA Seagate 320Gig SATA External 1T

Well, its my friends iPod. He told me he tried it on his friends computer and no connection there either... I already checked if the computer detected it in any way(throught the "device connected"beep and in My Computer), no luck... My iPod works on his computer though, so it is the iPod.
