i got my ancient UA-1000 working in win10 by using the vista(!) x64 drivers:
have the driver package downloaded and extracted somewhere,
plug in the device & power it on,
wait for windows to do its thing,
then in device manager it had the warning icon,
right-click it, choose "update driver software",
then choose "browse my computer for driver software",
browse to the extraction point,choose the driver
ta-da
maybe you can have similar luck? i'd never have considered the vista driver unless i;d read it on a (french) forum
hth
good luck!
