lsmod shows the _kernel modules_ that are currently loaded, and which other loaded kernel modules are dependent on it. lsmod is not the correct command to check whether "CUPS is running", because CUPS is a user-space service, not provided by a kernel module. If the host on which you're logged in is the CUPS server, then a "ps aux | grep cupsd" should show the /usr/sbin/cupsd daemon process running. If you're logged in to a client machine that accesses a remote CUPS server, then there may not be a local CUPS daemon (depending on the specific CUPS configuration). In any case a "lpstat -t" command should show whether the printer(s), whether local or remote, are ready to print and whether they have jobs on their queues. The "info" or "man" command is your friend, when it comes to looking for help on specific commands. E.g., "man lsmod", "man lpstat", "man cupsd", etc. -Ti -- Ti Kan http://www.amb.org/ti Vorsprung durch Technik

Try changing the printer port to /dev/usblp0 instead of that. What you have is some new way to access usb peripherals that does not always work.

I'm getting the same here and I've been at it for a couple of hours, without getting it to work, I may try building xscanimage and see if that will do it. As always, vuescan from http://www.hamrick.com automatically finds and is able to use the scanner without any need for configuration.
Check the module is loaded.
lsmod|grep usblp produces: usblp 13568 0 usbcore 113520 7 usbserial,hid,usblp,ehci_hdc,uhci_hcd
my /dev contains: /dev/scanners/cuecat
That's always there, presumably for if you have a cuecat.
am I supposed to have a matching entry in my /media directory as I have for other usb devices?
My /media is empty as I haven't got anything mounted, it's only for mounted devices like floppies and CD's.
what is udev ?
udev builds devices in /dev whenever you boot up.
Yast detects and installs my hp 6110 scanner.
YaST says it's configuring drivers for it, but doesn't detect my scanner.
But then The GIMP says "No devices available"
should I have an entry in fstab? The only usb entry I have in fstab is: usbfs /proc/bus/usb usbfs noauto 0 0
/etc/fstab is OK.
The quoted reference: http://www.avasys.jp/cgi-bin/lx/bbs/en/scanner-bbs/hyperbbs.cgi?mode=view;Co... says that I should have an entry /etc/hotplug/usb/libusbscanner script I have the directory(s), but no script.
Same here.

YaST doesn't even see mine.
Yast auto-detects the correct printer. If I try to connect directly via usb the test printer fails, if I try CUPS I have the choice of CUPS client only (which I chose) or networked.

No errors under /var/log/cups/ ?
Part of my confusion might be in not understanding the jargon: since it is a stand-alone machine, my machine is the server for CUPS - right? yes it is.
I have asked this before, and am embarrassed to ask it again: When I set up my ADSL I was prompted for something like "Server name" and I gave my ISP name, which now appears in my root prompt. How do I change it back? Sid, I think it was you who told me how to change it back, but I cannot find the method :-)
Your server name should be what your local machine is called rather than the ISP's as you are setting up the machine as a firewall for any other boxes on the LAN.
I am sorry that this is so complex. Thanks for all your efforts. Regards, Colin
It's quite frustrating, for the printer, all I can think of at present is to have another go at "lppasswd -a root". On the scanner, all seems to be as it should be, but it's not working for "scanimage -L" or xsane, but is fine with vuescan. Hmmmmmmm.... after running vuescan, kooka now finds my scanner with the epson setup in YaST. barrabas:/ftp/May05 # scanimage -L device `epson:libusb:002:009' is a Epson Perfection610 flatbed scanner For vuesca82.tgz .... # mkdir /usr/local/vuescan # cd /usr/local/vuescan # tar zxfv vuescan82.tgz in that directory, then # ln -s /usr/local/vuescan/vuescan /usr/local/bin/ # vuescan Regards Sid. -- Sid Boyce ...
