There should be a directory below /proc/scsi for your driver, named
aic7xxx. If this directory doesn't exists, the driver isn't loaded.
modprobe aic7xxx
in this case.

If the driver is loaded, you should read the documentation regarding 
your driver under /usr/src/linux/Documentation/scsi, maybe there's 
more information in /usr/src/linux/drivers/scsi also.
Is it a card with BIOS? If yes: enter the BIOS to make sure your card 
is probing the appropriate SCSI-Id. In some cases, the device isn't 
found if it is not probed at boot.
Is your scanner turned on at boottime? You cannot connect a 
SCSI-Device at a later time (in fact you can, but that's a 
complicated procedure)!
