There appears no /dev/sr for the passthrough drive. Since libburn

There appears no /dev/sr for the passthrough drive. Thus libburn will not

list it by its drive search function. One may use it nevertheless. But

xorriso will only do so if prefix "mmc:" is used with the address:

{{{

The drive will be listed by libburn if there is a symbolic link /dev/sr*
|

pointing to it. On Debian 6, this link persists only if it is created
|

by an udev rule.
