Thank you for help.

I did something similar before (following man jail, the section about 
creating devices in jail), the printer was printing from shell (master 
and jail), but cups did not recognize USB Printer #1 (not in jail nor in 

I spent a few moments/hours of my life and found out (installed clean 
test machine with DF and jail) that if I compile cups with gcc34, cups 
does not list the USB Printer #1. If I compile cups with gcc2, the USB 
Printer #1 is there.

But in jail I can't manage printer after it was added.

Cups error:


Is this a general cups problem or it's just the unusal combination of 
me+cups+gcc34 ? :) Has anyone else met the same problem?

I'm using 1.2.6-RELEASE.

Well, make it. MAKEDEV ulpt0 in the jail. But keep the security
implications in mind.
I could do the same thing in FBSD 5.4 and it worked. I was also looking 
how to mount devfs from master to jail, but had no success.
No devfs in DF.
