Just rec'd my UCX today.  Have installed updated firewire driver and Fireface settings show version 3.14.  When I run the flash update tool I get a message that reads "No fireface driver or device installed.  The UCX shows "FA" with a flashing green light.  No other lights active.  Host light only comes on when computer is off.  I have installed current firewire and USB drivers.  When I click the knob it cycles thru FA, PH, and SU.  The flashing green light appears when SU and FA are selected.  No other lights indicated.  I have no idea what's going on or what to do next?
