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.
