It used to work, but it's been a long time since I've had access to that 
hardware.  You should uncomment the line in the driver defining 
PCIDAS64_DEBUG, which should generate kernel debug messages you can see in 
dmesg or your system log files.

Also, it looks like, you're editing the wrong function in demo/cmd.c.  
prepare_cmd() isn't used by the unmodified cmd.c
