I'm not sure what package this needs filing under for BZ, but
when I run
the cups web front end, it is reporting that usb:/dev/usb/lp0 is failing
to open. s-c-p is showing my Deskjet 980cxi happily when setting it up,
but am unable to print.
When I've looked in /dev, there is no usb directory (and therefore no
lp0 either).
Is this a makedev problem, s-c-p or something else?
This is probably
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=180325
Try:
mkdir /dev/usb
ln -s /dev/lp0 /dev/usb/lp0
service cups restart
If this "fixes" it (until the next reboot), then you are seeing #180325.
