Ya, I havn't did thing what you want but for sending SCSI Commands to
the SCSI Device directly you have to use SCSI Protocol, in
Kernel-2.6.x I found generic SCSI Mid-Layer Driver
(http://lxr.linux.no/source/drivers/scsi/scsi.c) and other files with
name scsi_* in drivers/scsi/ from which you can get help and also look
header files defined in include/scsi/ which actually has the
structures holding the SCSI cmnds etc ...... (CMIIW)
