if you plug your phone into your computer via usb, i choose "disk drive" off the connect to pc menu.
once your phone pops up onto your computer, i just drag my music into the Music folder,
if this is what your questioning about?
USB works for me. Though when you plug the phone in to your computer, two different drives appear in My Computer after you select Disk Drive on the phone. Only one of those drives lets you copy files to the phone. If one doesn't work, then try the other.I tried this and it didn't work.
