For the initialization sequence, you could refer to drivers/scsi/scsi_scan.c. You could get some more documentation at chapter 5 in the pdf below.

Dear all:
Would you please tell me where I can find the SCSI initial sequence?
Since I read the spec, I want to know the sequence of using them.
For example, if I plug in a usb flash, what are the correct and proper

appreciate your help,
miloody
