Debian                                            June 16, 1998                                      DEVCLASS(9)

       The  devclass object has two main functions in the system.  The first is to manage the allocation of unit
       numbers for device instances and the second is to hold the list of device drivers for  a  particular  bus
       type.  Each devclass has a name and there cannot be two devclasses with the same name.  This ensures that
       unique unit numbers are allocated to device instances.

       Beware that this means devclass must be the same for different bus attachments of the same device driver.
