| Card Reader | 
For a card reader they usually do not provide media change information and so the kernel can not generate a hotplug event for udev. In this situation you can use the all_partitions property for the NAME. To get access to a CF slot on a specific multi-card reader:
| 
  BUS=="scsi", SYSFS{vendor}=="Zynet*", SYSFS{model}=="USB Storage-CFC*", 
  NAME{all\_partitions}="compact\_flash"
