Thanks, I had seen that. Still I quite don't get it. What management are 
we talking about? I've always thought of hot plug devices as dumb 
connectors...

Furthermore:

# pwd
/usr/share/examples/ses/getencstat
# ./getencstat -v /dev/ses0
SESIOC_GETNOBJ: Inappropriate ioctl for device
# ./getencstat -v /dev/da0
SESIOC_GETNOBJ: Inappropriate ioctl for device
