Strange. The next step in sanei_scsi_open after the DBG statement for
sanei_scsi_max_request_size is to open the device file and to issue a
few ioctls. Since you are using kernel kernel version 2.4.17, the next
thing you should see is something like

"[sanei_scsi] sanei_scsi_open: SG driver version: xxxxx"

Do you get any related error messages in /var/log/messages? Which low
level SCSI driver do you use?
