[PATCH] USB: Add one VID/PID to ftdi_sio

This patch adds the Testo USB interface to the list of devices
recognized by the ftdi_sio module. This device is based on a FT232BL
chip, and is used as an interface to get data from digital sensors
(thermometer, etc). See http://www.testo.com/Signed-off-by: NColin Leroy <colin@colino.net>
