When I plug my 7130e into a USB port on my laptop, it charges the phone, very nice. But when I plug the 7130e into a powered usb port on my inverter, it doesnt charge. I know that this powered usb port on the inverter works because I use it to charge my iPod (and other USB toys). As well, I just plugged the phone into a friends laptop and told it to cancel when it found new hardware, and it didnt charge.
So that implies that you have to have software installed to USB charge? bummer.
Does anyone know if this is a setting that can be changed on the phone? So that I can charge it off of a powered usb port without a computer.
