That is how a SCSI driver would determine if SCSI drives are attached, send an 
INQUIRY command to each device address and wait for the command to either 
complete with data or time out.

I think currently the best approach would be to use some type of configuration 
approach as you have suggested, and investigate enhancements to the driver 
for auto detection and configuration in the future if someone has time to 
work on it.  The last time I checked, there was a comment in the driver to 
the effect that DMA operation had not been tested yet, so it seems there are 
some enhancements which would be useful, but might be too intrusive to 
include on short notice.
