cupsd USB problem

moger · 09-13-2004, 07:01 PM

I installed cups successful for a Brother Hl-1440. I installed the correct .ppd file, etc. However, in cups' web based configuration, it says ""Unable to open USB device "usb:/dev/usb/lp0": No such device" . Also when I ..

Code:

lsusb -D /dev/usb/lp0
 Cannot open /dev/usb/lp0

I got USB enabled as a module. Did I miss something? Here are my modules:

If you go (in KDE) to Control Center > Peripherals > Printes > Add (menu) > Add Printer/Class

and follow the wizard, what ports does the wizard show as awailable?
(it sould give you a tree of Com/ParPort/USB/SCSI, expand the USB branch)

swissworks · 09-14-2004, 07:27 AM

I have the same printer and I have some problem...
Cups works fine, but sometimes hungs up and stops to work..... And I have to reinstall packages...
I think there is some bugs....

Is it mounting to /dev/usblp0 perhaps? I know cups wants to print to /dev/usblp0 but my printer gets mounted to /dev//usb/lp0,

Just a thought...

I use GNOME.

And I don't see any printer config utility in my gnome.

I'm not shore, but why /dev/usb/lp0
it should be /dev/lp0
when you config it with your browser at http://localhost:631
write this and after that choose usb printer #1

What do you mean? Write "/dev/lp0" where?

moger · 09-14-2004, 12:47 PM

I changed the line in the printers.conf file from /dev/usb/lp0 to /dev/lp0, restarted cupsd. And I get this:

Printer State: processing, accepting jobs.
"Printer not connected; will retry in 30 seconds..."
Device URI: usb:/dev/lp0

Edit: I'm thinking it's a USB problem, but I got all the USB modules loaded don't I?

moger · 09-14-2004, 02:32 PM

I got it working finally. I didn't have a few USB modules loaded in my kernel, mainly uhci. Even after that it didn't print, because I had to use usb:/dev/usb/lp0 in my printers.conf. I changed that to usb:/dev/lp0 after "Ipolit" told me to.

Ipolit · 09-14-2004, 02:33 PM

why don't you try to configure your printer as I mentioned using browser
http://localhost:631
log as root
add a printer, etc
It's easy

obviously that is what I was doing. It wasn't recognizing any usb devices because I was missing a few USB modules.

Interesting... It won't print at 1200 x 600 DPI but it will at 600x600 DPI. Now this laser printer ( Brother HL-1440) should be able to print at 1200x600; it has enough memory and does it fine in Windows. Any ideas?
