USB data communication fail
Hello! I got a used iPod Video 5th gen "enhanced" (5.5) that can't connect to the computer at all (Windows or iTunes). The device initially showed the sad ipod icon when connected to a power source or the computer.
After testing it, I found out the hard drive is damaged, but even after swapping it with a working HD, the logic board won't make the connection with te PC and shows the connect to itunes to restore message. Booted the ipod in diagnostic mode and it fails to recognize a USB cable when connected to the computer (IO>USB Test>No Cable Conn), but it seems to charge just fine from USB.
Now my questions are: which chip in the logic board is the USB controller? Could it be that the solder on the chip cracked like it happens with the Wolfson chip and no audio comes out from any port? Maybe a "reflow" could help? Anybody with a similar experience? Thank you very much in advance, and sorry for my subpar English.
