Re: USB printer difficulties
wht the heck are major/minor numbers?!?
>
From Rubini's "LINUX Device Drivers", P.43, 44:
Char devices are accessed through names in the file system, usually located in the
/dev directory. Device files are identified by "c" in the first column of the output of command ls -l.
You see two numbers, before the date of last modification, {seperated by a comma) on device file entries. These numbers are the major and minor numbers.
The major number identifies the driver associated with the device. Adding a new driver
to the system means assigning a major number to it.
The minor number is only used by the device driver. It provides the driver with a
way to distinguish between multiple devices which it may control.
I hope this answers the question.
