|
Printing in Linux is going to be the death of me. Everytime I look at my computer wrong, printing breaks. OK, now that I got that out of my system.
For various reasons I decided to re-boot. Since I was rebooting I thought I would go with the latest sources so I tried gentoo-dev-sources 2.6.9-r1. Everything looked fine but I can't print. CUPS says that /dev/usb/lp0 does not existing. After opening a terminal and looking the /dev directory I can see that it does not exist. CUPS starts and restart without problems. usbview and lsusb both show that I have an APC UPS and an Epson printer. I saw another thread that says that CUPS won't start and usbview and lsusb do not show their printer. My problem seem to be something else.
What is going on and how do I fix it?
Thx

udev I believe. I have had udev installed for quite a while and the /dev filesystem is disabled in the kernel.

I gave up and went back to 2.6.8 and all is working again. With 2.6.9, neither my printer nor my ACP UPS would work. It looks like a problem with 2.6.9 and USB. There is another thread about CUPS hanging. CUPS did not hang for me it just wouldn't print because there is no /dev/usb/lp0.

Did you select the "USB Printer" option on your kenel config? If it is a module, did you | Code: | | make modules && make modules_install |
?
On 2.6.9 I've found it is necessary to make modules. Just make all makes the bzImage, not the modules.

Thanks for the reply. Yes I do have USB printers and I always build the kernel with | Code: | | make && make modules_install |
I moved on to nitro and it has been working.
Thx

Thank-you!
I was going mad with trying to get a USB printer working until I saw your post and it all became obvious why /dev/usb/lp0 wasn't magically appearing. Yippee!
