Problem USB Charging an O2 XDA IIi

[Philip Sheard]

I am trying to charge an O2 XDA IIi device with a sync/charge cable, but it seems to discharge the battery instead of charging it. I have tried with different devices, different cables and different batteries, but the same thing happens every time. Am I doing something wrong, or is there something I do not know about?

maybe USB CABLE or PDA's Connector 13－15pin have some wrong.

it happens only when connected to cable or also when cradled?
There is a possibility that the connector on the device itself has bad contacts either on the pins inside the socket or the pins which are soldered to the device's PCB inside the device (you cannot see them from the outside if the device is not disassembled).
