1-wire sensors not showing up

I am using the USB 1-wire DS9097 adapter i got from ebay. When I use the dallas 1-wire reader in weather display none of the sensors show up. But if use the maxim 1wireveiwer all the sensors show up fine.

do you have the correct adaptor type and port selected in the wd 1 wire reader?
also you could try using the installed 1 wire dll files copied into the WD folder (the IB*.dll files)
