Hello when connecting my iPod to my laptop. Comes following message: As a USB device withdrawing too much power from your computer, one or more USB devices disabled.
What can I do?
If you have the new 5G iPod that typically indicates a defective Lighting cable (the cable that goes between the iPod and your computer). Apple will replace it at no cost if defective. You can do it an Ap[ple store
