Hi

I have tried to install a usb printer but I have no /dev/usb.

Usb drivers / usb printer installed (in kernel / module)

Do I have to create the folders /dev/usb and the things that are in there ?
Why ? ;)


thanks

If you are not using devfs, yes.

Ok, it is in development, thats fine ;)
It works now, I've found a mknod command in the newsgroups.

Is there a document for mknod which explaints the numbers at the ond of the 
command. The manpage is not really good.

thanks
have fun

Heh, no it's not in development.  Sorry for giving you such a short
answer, but it was a short question, with a lot of needed information
missing :)

Your distro should have set up all of the /dev nodes properly.  If you
are using an old distro version (as I am guessing you are) you will have
to set up the missing /dev entries by hand.

All of the numbers are documented in the Documentation/devices.txt
file.  The Linux USB Guide at http://www.linux-usb.org/ also has info on
how to create the needed USB device entries if you're interested.

Good luck,

I'm using Debian unstable. I think this is new.
But Debian is not the best in "self doing linux", so thats ok ;)

What is mit devfs, it is experimental. But what is it's status.

Will it delete my files, will it toast my printer or will it only crash my 
system ?
If it ok, I think I could change to it.
