I open a new tread for this argument. I have Slackware current
with udev without hotplug. All devices work fine, except the
printer, a USB HP Deskjet 6122. The printer is correctly identified
(lsusb -v) and the driver is charges (lsmod -v). In /dev
/dev/lp0 is regularly created. I configure the printer by CUPS
via browser, but when I try to print, CUPS tells me:
================================================== ====
HP DeskJet 6122 Foomatic/hpijs (recommended)
Description:
Location: locale
Printer State: idle, accepting jobs.
"Printer not connected; will retry in 30 seconds..."
Device URI: usb:/dev/usb/lp0
================================================== ====
Instead, another USB device, the scanner, works regularly.
Any suggestion?

Thanx!
MS

My HP 845c has

DeviceURI usb://HP/DeskJet%20845C?serial=TH25T130VFSX

Considerably different don't you think? In fact there is no
reference to lp anything in any config file for that printer.

Do u wrote a new udev rules?
Do u receive that configuration
in another way?

Thanx
MS

I have exactly the same problem with my hp 940c after last uprading
udev to slackware-current

Ok... /dev/lp0 is created

but it is looking for /dev/usb/lp0

They are not the same. I'd either reconfigure CUPS to look for
/dev/lp0 or rewrite the udev rule to write /dev/usb/lp0.

Actually, I'd probably do both. Make udev create a symlink to
/dev/printer or /dev/deskjet6122 or something similar. Then I'd
reconfigure CUPS to look for that.

The version of udev in slackware-current is .064 which is almost a year old
( the concept of 'current' in Slack does not mean that it has the 'latest'
packages from upstream. )

The latest version of udev for the 2.6.x (required) kernel is .091. You
might get this version at
http://www.us.kernel.org/pub/linux/u...ernel/hotplug/
and give it whack.

For what it is worth, in the Debian world udev is under almost constant
change (some say it is constantly broken). In the Sid repository we get a
new version almost every ten minutes!
http://packages.qa.debian.org/u/udev.html

I've had no problem with my Palm, jump drive, or camera, using udev but I've
not tried a USB printer. And on the deb boards I don't see too many
postings about printer problems and udev with cups. It's usually udev with
an external USB hard drive that you see postings.

In -current, you will find 071 which is also the minimum required
version for recent 2.6 kernels.

I know, but I've the Peter Punk's udev version (i. e. 0.90).
And not able to print if I don't adopt hotplug....

Nothing to do with /dev, cups no longer uses /dev for usb
printers.

Run '/usr/lib/cups/backend/usb' to get the URI for the usb
printer, or just select the printer from the web interface
when you set it up.
