I'm trying to setup my usb printer according to the gentoo printing guide but where the hell is the usbcore module I get this when trying to modprobe usbcore

modprobe usbcore
Segmentation fault

usblp loads fine but doesn't find a printer when i tail -f /var/log/message I'm using kernel 2.6.5 anyone know what I'm missing?

The module "usbcore" only applies if you didn't compile USB support directly into your kernel. If you have hotplug enabled in your kernel and you plug in your printer, dmesg should show that your printer is dynamically installed.

Are you using udev or devfs?

Which guide are you following? The Gentoo Printing How-To is good about telling you which packages to get, but you should find specific instructions at [url]hpinkjet.sourceforge.net[/url]

Yes I am following the gentoo printing guide however I've gotton printing to work on gentoo before as well as freebsd I have a feeling I'm missing something =\

HP is weird. Assuming you have a usb printer, you might not be able to access it at all without the drivers properly configured. Is there a /dev/lp0 or /dev/usb/lp0 entry at all? If not, show us your usb bus with this command:

Are you running the latest version of hpijs and ghostscript? You'll also need to worry about what print manager to use, though most people, including myself, go with CUPS.

cat /proc/bus/usb/devices
cat: /proc/bus/usb/devices: No such file or directory

No there is no /dev/lp or /dev/usb/lp device listed which is where I have the problem =\

Have you been able to get any usb devices to work? Please consider recompiling your kernel. You can find usbcore under Device Drivers->USB Support. Select "Support for Host-side USB", "USB device filesystem", one of "EHCI", "OHCI", or "UHCI" support, and, of course, "USB Printer support". I recommend compiling each of these into the kernel except for "USB Printer support", but that's a personal preference. Then the only module you will have to load is usblp. Of course, you can compile printer support into the kernel anyway and have no modules at all to worry about.

Are you using udev or devfs? If you don't understand the difference, one is a separate program, while the other is compiled into the kernel. The Gentoo Handbook currently still recommends devfs.

If you had your printer plugged in when you ran genkernel, it might have discovered it for you.
