Now I am working on a new scan routine for CAM. I'll probably publish
patches in a few days. If your card reader (AFAIK there are USB-based
one) will be able to register it's SCSI bus to CAM before the rest of
CAM-supported controllers (for example, ata(4) with ATA_CAM) finish
their scan, new routine will manage system waiting for it also. It not -
it will be a another question.
