What are you agreeing with him on? Why not quote what you're talking

If you want a bus number, there's a really easy way to get it:
# camcontrol devlist
<EXABYTE EXB-10i 2.6> at scbus0 target 3 lun 0 (pass0,ch0)
<EXABYTE EXB-8500-85Qanx0 0415> at scbus0 target 4 lun 0 (pass1,sa0)
<SEAGATE ST31230W 0510> at scbus1 target 0 lun 0 (pass2,da0)
<SEAGATE ST32155N 0318> at scbus1 target 1 lun 0 (pass3,da1)
<PLEXTOR CD-R PX-R412C 1.04> at scbus1 target 3 lun 0 (pass4,cd0)
<PLEXTOR CD-ROM PX-4XCS 1.04> at scbus1 target 6 lun 0 (pass5,cd1)
<SEAGATE ST34371N 0484> at scbus2 target 0 lun 0 (pass6,da2)
So, in this case, the bus,target,lun combination for my CD-R is 1,3,0.
cdrecord itself also has a slightly more obtuse way of doing the same
thing:
# cdrecord -scanbus

The camcontrol output is easier to figure out, though.
