Also look in your boot logs to see what the SCSI driver is doing. Here is an example from my dmesg log file showing that I have a couple of LSI Logic 53c1010 dual channel controllers. Note the section towards the end where it shows the devices being detected on the SCSI bus's. The Vendor: HP, Type: Processor is my scanner.
