Hi

The most common cause for no device showing up is the device is not being powered correctly.  When you assembled the 1 Wire Pi Plus did you fit the jumper to the two holes next to the R2 multiway resistor above the AD1 jumper?  If you have access to a multimeter could you check the 5V and GND on the row of pins next to the RJ12 connector to make sure there is 5V present on the board.  It may also be worth checking the GPIO connector and the RJ12 connector carefully to make sure there are no bridges or dry joints.
