Subject: cupsys: problem with USB backend
Package: cupsys
Version: 1.2.0-0ubuntu5
Severity: important

After an upgrade to dapper, my USB printer stopped to work. Using cat
>/dev/usb/lp0 I am able to print, but not with the USB backend.
The USB backend says it is unable to open the USB device, however from
the strace output it seems the backend does not even tries it.
Strace output is at the end.

Yes, I tried to reinstall cupsys after installing everything with the
name containing libgnome and (perl or print).

Thank you! Your information will help fixing this bug.

[Ante Karamatić (ivoks)]

You have /dev/usb/lp0 on Dapper? Or is it /dev/usblp0?

The original reporter is not subscribed to this bug report yet (he used the reportbug command to file his bug). I have sent him an email asking him to login into Launchpad a few days ago.

[Ante Karamatić (ivoks)]

Tell him to update to Dapper's kernel :)

Update for usb backend:

"URIs of the form "usb:/dev/usb/*" are no longer supported in CUPS
1.2, largely because those device names are not stable, i.e. the
number will change on you whenever you boot, cycle the power on the
printer, or disconnect/connect the printer."

[Matthias Urlichs (smurf)]

It seems that the USB backend tries the wrong printers.

It tries /dev/usblp0 and /dev/usb/lp[0-15].

However, udev on my machine creates the printer as usblp[0-...]. There are no special rules, so the device name seems to come from the kernel.

Thus, the second printer is never found.

[Matthias Urlichs (smurf)]

turns out to be a different problem -- never mind.
