Hi,

I am trying to add my USB printer through CUPS.For that USB device is not listed under the cups page.When i checked I am missing /dev/usb in my file system.Please help me on this.I am using Fedora 7.

There is no such thing as /dev/usb . You can check /proc/bus/usb/devices for a list of devices that Fedora has found attached to your usb ports. You'll need to cat out that file, it's not a directory. You should not need to go this far low level to get a printer working. You should only need to connect the printer via usb, open the printer administration tool "system-config-printer" , then add the printer there

Hi,

Thanks for your reply
I tried cat /proc/bus/usb/devices and it list my smart card printer .I am developing the driver for this printer.I need to add this through CUPS.SO in the cups device page ,USB device option is not there to attach my printer.How to get that listed?

Explain in detail the steps you are taking to add this printer, what you are "expecting" to see, and where you're stuck.

I'm trying to follow along with what you might be having an issue with. I'm assuming that you're opening up system-config-printer and go to New Printer. Then you're looking for USB under Select Connection. Is that correct?
You need to select Other and set device URI to the correct usb port you have it connected to. This will be /dev/bus/usb/[001,002,003,004] or whatever it shows under /dev/bus/usb/

**EDIT**
If you don't know what device your printer is plugged into you can check "dmesg" and grep for usb. IE -> "dmesg | grep usb". Make sure your printer is attached and powered on before doing that or it won't show up in dmesg. You could also do "tail -f /var/log/messages" and then unplug the usb cable, then plug it in and watch the logs live for the messages you need.

To search for all usb devices you have do "find /dev -name usb* -print"

Ok so what options are you seeing then? Parallel should be one, HP Jetdirect should be another. What connection methods are listed for you?

Also, are you running the Smart Card Daemon?
sudo /sbin/service pcscd start

Then unplug, re-plug the usb printer

Hi,

I already tried pcscd option.But it didnt help

Options i can see
Applejet,HP,Serial Port,Http,ipp,lpd,lpt
All r there except USB.

Also when i plugin my printer,/dev/usb directory is also not created.Is that means linux usb printer driver is not detecting my USB printer???

Please help

Hi,

Why /dev/usb is not creating for me when i connect my smart card printer.I am using to create the device driver for my printer.In CUPS backend for usb is checking the dir /dev/usb.
