Default How to make a custom USB cable for a Finis Neptune MP3 player?

Someone gave me a swimming, underwater Finis Neptune MP3 player but the problem is the charging cable was not included. Since this is a waterproof MP3 player the cable is proprietary and it is impossible to find a cable (from the company or otherwise) without buying a second unit on eBay with the cable.

My 1st question: Is there a way to cut apart an old USB cable and make my own charger/transfer cable?
My 2nd question: There are four contacts on the bottom of the MP3 player. How do I map each one to know what is positive, negative, ground and data transfer? (Photo of pins attached)


Thanks!

You would need schematics of the circuits used to charge the battery. Also knowledge of how USB cables transfer energy. Why are you so sure you'd need to modify a USB cable and not something else?
