When I had an epson inkjet printer I don't recall having that problem, but it's been a while.

It should _not_ be in /etc/devfs.conf, since usb devices can appear at runtime. (The first line is only needed when you haven't already got a ruleset name.)

Roland Alternatively, just put this in /etc/devfs.conf: own ulpt0 root:cups permulpt0 0664 That's all I had to do to get my cx4800 printing with ulpt and cups. FYI, the cardreader on my cx4800 works when ulpt is NOT loaded or in the kernel but umass is. Similarly, the scanner only works when neither ulpt nor umass is loaded or in the kernel. It doesn't attach to uscanner but it works with libusb.

Thanks Roland, I put what you have said to /etc/devfs.rules and it printed the test page well =) The only problem now is Epson Inkjet Tool that shows ink levels, cleans heads, etc when I click on Show ink level it tells: ERROR: Cannot open /dev/ulpt0 read/write: Permission denied pgpNc0BJFAaX5.pgp Description: PGP signature ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Basically you have two choices here, 1) Change the mode for ulpt0 to 666. This means everybody can read/write to this device. This is unsafe on a multi-user system or on a publicly accessible server. 2) change the group of the program to 'cups', and set it's setgid bit (chmod g+s ...). This means that the program will assume the group 'cups' when it starts, giving it access to the device. IMHO (2) is the best solution, because it gives the program in question enough rights to work, without exposing the rest of the system much.

Re: Anyone could make Epson Stylus cx4700 work?
Well, I did this and now the permissions look like this: -r-xr-sr-x 1 root usb 72504 May 15 13:01 escputil and if I execute the program being in my user it tells permission denied. Another problem is that when I executed it in root, it showed #escputil -iur /dev/ulpt0 Cannot open /dev/ulpt0 read/write: Device busy There is no printing job, and in the control panel in kde I can see that printers state is Idle (accepting jobs). ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Yes, because escputil belongs to the 'usb' group. It should belong to the same group as /dev/ulpt0, which should be 'cups'. A 'chown :cups escputil' should fix that.

I think you need to drop the -r option, (and -u as well). Cups is probably already using the device.
