commit 0b641dac717ffe1391cc53dc33ad78ba79a26d2c

    read target voltage first in vsllink
    
    The very first command after init command should be "read target voltage".
    
    This is a tweak for the Old Versaloon firmware.  Without this, in most
    most cases, it works.   Under Ubuntu9.04, there is a chance that the USB
    will fail.  The problem disappears if I read target voltage first.
    
    For the lastest Versaloon firmware, it's OK.
