Btw, this properly initializes Platters (LUN) 0-3 on my CD ROM
changer, and although Platter/LUN 4 and 5 are mentioned in the syslog
/dev/sr5 and /dev/sr6 are not useable afterwards. (The changer starts
at /dev/sr1 ...)

Btw, the feature works great after turning on my external streamer,
which has a fan that probably has been a hovercraft engine in it's
before life ;-)
