I have an ipod shuffle. Most of time, I play Xiangsheng on it.

It uses an usb cable to charge the battery and also connect with itunes to tranfer data.

The cable I have is not that sable. I have to put it in a particular position to make it conneted. So, I think there is a broken ponit fo one wire.

I decided to fix it by my soldering skill

From the picture, you can see the part I cut and reconnected it.

I am alos using digital multimeter to double check the soldering and connection.

The pinout map is gotten from here. I put it below for future reference.

After everything done. I plugged into ipod shuffle, and usb into the PC. itunes find it automatically.
