USB ADSL tester



Jan 1, 1970
Does anyone know how to run an ADSL USB modem from a 6v battery? I need to
use the modem to test for line synch. without having to start up my laptop
every time. I have tried connecting voltage to the +ve and -ve pins of the
USB cable but without a computer connected, it will not fire up. It must
require some sort of data signal on the other leads to make it work. I have
tried two different brands of modems but with the same result.
