Question rised:

Is it better the approach of "# echo >/proc/scsi/scsi "scsi add-single-
device x 0 0 a" where 'X'=scsi channel, and 'a' value from 1 to n-1
(N=max LUNS in the card reader) than this actual of modifying the kernel
module option? I mean, to try to minimize the risks of having kernel
oops in automatic probing luns. 

Since Fedora folks are whitelisting this units that leads me to that
conclusion and im not sure about it and not an expert ...

Ideas allways wellcomed

Jose
