xsane says failed to open device hpaio:/net/ device busy

Asked by Bruce Dawson

I'm running Ubuntu 6.10 with HPLIP 1.6.9 and can't scan from an HP-2840. But I am able to print to it without problem.
xsane sees it (actually, it sees two of the same device), but when I select one and click OK, it responds with "Failed to open device `hpaio:/net/HP_Color_Laserjet_2840?ip=192.168.56.13': Device busy.

/var/log/messages produced the following while running xsane:

 Thanks for the prompt feedback.

The scanner used to work from both Windows and Debian, but then I
switched to Ubuntu and it hasn't worked since. It also no longer works
from Windows.

There's no hp-check on this system. I believe it doesn't come with
Ubuntu. However, hp-info did find the printer, and its output is in the
original report. Also, note that xsane appears to see the printer, but
can't communicate with it.

Okay this just means that you are using the preinstalled hplip.

Please run

groups

and post the output.

Also if it's possible please upgrade to the latest hplip..

Thanks!

Output of 'groups' is:

jbd@bruce:~$ groups
jbd root adm dialout cdrom floppy audio dip video plugdev staff lpadmin scanner admin milessmithfarm.net

Upgrading to the latest hplip is not viable at this time (the system has
to come out of production, and that means a new system is required, and
things just go downhill from there.)

We haven't been able to reproduce this with the latest hplip. If possible please updated to the latest hplip and that may resolve this problem.

Hi,

I solved the same problem by setting SNMP community settings to
  Read: public
  Write: public

I got this solution by sniffing the traffic between 2840 and host computer.

Kind regards,

Marcel Straub's answer worked in my scenario (HP Color LaserJet 2840 / Sane on both Ubuntu 10.04 and CentOS 5.5).
The error would either be "device busy" or "Error during device IO" when trying to connect to the JetDirect hpaio:/net/ etc. backend.
(re-)enabling SNMP write solved the problem.

thanks!

Enabling SNMP write on the printer did solve the problem. Of course, this does open up security issues, but I'll post another question if I can't get them resolved.
