It sounds as though the Data cable in your charging lead may be faulty. Do you have another lead to try? The Olfi White and the 1st Gen one.five both use Micro USB connections, the newest Black version utilises the mini USB port due to the external mic connection. Can you please confirm when your camera was purchased and which camera version it is?
I am happy to send you a replacement cable, i just need you to answer the questions above and let me know your preferred delivery address (i suggest you e-mail me these bits 🙂
looking forward to hearing from you
