    Depends on the driver.  For AHCI, if the AHCI chipset has the
    appropriate support it should detect the insertion automatically.
    If it doesn't then the port might not support hot-swap detection
    and camcontrol won't have any effect.

    That might make a nice mini project, though... to have the AHCI driver
    handle the SCSI bus-reset command from camcontrol and force the port
    into a hard reset sequence.

    For NATA/IDE attachments (adXX) you might be able to use natacontrol
    to force it to rescan the bus.

    For other devices it depends on the driver.
