The scsi generic device is listed as a child of the parent
of the mapped disk device. E.g.

  +- pci_0000_00_1f_2
  |   |
  |   +- scsi_host0
  |   |   |
  |   |   +- scsi_target0_0_0
  |   |       |
  |   |       +- scsi_0_0_0_0
  |   |           |
  |   |           +- block_sda_TOSHIBA_MK5061GSY_9243PG8CT
  |   |           +- scsi_generic_sg0

This is consistent with the sysfs/udev.

The XML produced by udev backend:

<device>
  <name>scsi_generic_sg0</name>
  <path>/sys/devices/pci0000:00/0000:00:1f.2/ata1/host0/target0:0:0/0:0:0:0/scsi_generic/sg0</path>
  <parent>scsi_0_0_0_0</parent>
  <capability type='scsi_generic'>
    <char>/dev/sg0</char>
  </capability>
</device>

The XML produced by HAL backend:

<device>
  <name>pci_8086_2922_scsi_host_scsi_device_lun0_scsi_generic</name>
  <path>/sys/devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/scsi_generic/sg0</path>
  <parent>pci_8086_2922_scsi_host_scsi_device_lun0</parent>
  <capability type='scsi_generic'>
    <char>/dev/sg0</char>
  </capability>
</device>
