|@Helmut -- touchy! Preemptive is very good, but assumptions usually lead to false-starts, waste of time (for both sides), and the difficulties associated with trying to re-start fresh. I'm sorry that you took it personally. I have found myself "getting ahead of myself" too often, and have had many regrets over it.|
..."I assume that the device can be plugged into a computer with a USB connection"... is more than preemptive, is it not?
Anyway, maybe now the OP will understand the importance of providing as many relevant details as he/she can.
