I have an issue with charging my T1 at work which is where it is would be most handy. I plug it into the usb port on my windows pc and it's fine for a few seconds until the security software on the pc shuts down the mass storage device. The reader had charged for a few seconds but as soon as it connects it stops charging. This is quite frustrating.
My android phone, however, doesn't stop charging when mass storage is shutdown as it gives me the option to 'charge only'. I would very much like for the firmware on the reader to have this facility to charge, via usb, without having to connect the mass storage device. I feel sure you could do this and you should definately consider it for the next firmware release. TIA
