Slack 10 with kernel 2.6.10

Box used as a print server. mail server & file server. printing via CUPS

Suddenly usb printer stops responding.....printer & cables etc all okay.

dmesg reports no significant errors.

cat /proc/bus/usb/devices reports printer as normal.

tail /var/log/messages reports usb connect or unconnect as appropriate

ls /dev | grep usb gives which is kinda odd because that should be a directory with lp0 and its frineds in it.

Any one know why that's happened or how to fix it?

I just realised that it's kernel related.....I usually run the server on an original 2.4.26 kernel but i must have booted to a 2.6.10 that was there for me to play with. Must be some USb subsystem option somewhere...know which one?

Did you enable hotplug and udev ?

The usual hotplug bit seems missing in dmesg.

I'll try that and see what happens.

D'oh d'oh d'oh

USB printing option not enabled in kernel....simple yet symptoms weren't obvious.

I now have a lone lp0 in /dev/usb woohoooo

Hi, can I revive this thread? I have a similar situation, but can't
print.

I have slackware 10.1, with
cups-1.1.23-i486-1 and hpijs-1.7-i486-1.

I have all usb related kernel options either y or m in my
2.6.10 kernel.

I have an HP OfficeJet K60xi "All-in-One" printer.

cat /proc/bus/usb/devices --

lsmod shows usblp is loaded

I add my printer in the locahost:631 pages, all seems good,
(there were two identical choices for K60xi printer?)

I chose the USB Printer#1 option from the select list.

I try printing a test page or printing from the command line
but I get no printout! cups shows job completed though.

What can I do to find/eliminate the problem? Any help out there?

Thanks,
