I recently ordered a Motorola SYN0896A wired handsfree, including
pushbutton, which terminates in the same mini-USB plug that many of the
new Motorola phones use. The manuals describe this port as for charging
and accessories.
To my naive surprise, neither my wife's RAZR V3c nor my SLVR L7 recognize,
or display any indication whatsoever, when the I plug it into either
phone. The manuals are useless on this! Is there any hope of a wired
headpiece working with newer models?
