Hi again,

Ok, just clicking the "send mail" button revealed the solution ;)

# lsscsi
[1:0:0:0]    cd/dvd  QEMU     QEMU DVD-ROM     2.5+  /dev/sr0
[2:0:0:0]    disk    QEMU     QEMU HARDDISK    2.5+  /dev/sda
[2:0:0:1]    disk    QEMU     QEMU HARDDISK    2.5+  /dev/sdc
[2:0:0:2]    disk    QEMU     QEMU HARDDISK    2.5+  /dev/sdb

SCSI IDs match WUI scsiX numbers.

No sure wether that can be improved somehow? :-)

Thanks and sorry for the noise.
