I asked the same question recently about firewire.  You can force the
kernel to use specific devices in the SCSI chain, and the attached diff

The essence of all slavery consists in taking the produce of another's
labor by force. It is immaterial whether this force be founded on ownership
of the slave or ownership of the money that he must get to live on.
