Hello, AFAIK, the the major number identifies the device TYPES rather than devices themselves and no major number could be registered by more than one driver. My question is how does different drivers for different devices share the same major number then? NOTE: I am not talking of different device INSTANCES but different devices which have different device drivers. Thanks in advance. ------------------------------------------------- "All over the place, from the popular culture to the propaganda system, there is a constant pressure to make people feel that they are helpless, that the only role they can have is to ratify decisions and to consume." -- Noam Chomsky -- Kernelnewbies: Help each other learn about the Linux kernel.
