Sansa Clip will only charge

My sansa clip is normal and functional and used to connect to my PC, but it just doesn’t connect anymore. It can charge and I can still play music, record voice, etc. I connect my usb cable to my computer and my laptop and they both run windows XP and it won’t connect to either of them but it will charge. I borrowed my brother’s sansa clip and used the same cable and it could connect so it isn’t the cable or the computer.

Can anyone help?  :cry:

What USB mode is it set to? MSC mode provides the most reliable connections. Don’t use the Auto Defect setting.
