-OPTIX Instrument Not Recognized, Can't Uninstall Driver - PC

Symptoms:  Unable to communicate with DPT94.  Lacie driver ( siusbflt.sys ) appear to be linked to DPT94 in the hardware properties dialog.  Attempt to remove DTP94 drivers will lock up the PC. 

Workaround:  Go to add/remove programs and uninstall "LaCie Updater". This will not affect the operation of the hard drives. Reboot the computer before attempting to use the instrument.
