 This works for the NEC controller.  THANK YOU !!!
 
 However, it does not work for the VIA 6307 controller.  :-(
 FreeBSD remains in CYCLEMASTER mode.
 
 I tried it with and without "-u 0" ( VIA is bus 0  NEC is bus 1).
 I tried rebooting.  Nothing helps.

 # -u 0 is for the onboard firewire VIA controller
