[gentoo-user] usb scanner HP2200c

[gentoo-user] usb scanner HP2200c

[Mihamina Rakotomandimby (R12y)]

Hi,

I have an USB scanner HP2200c.

It is automatically detected and used with Fedora and Ubuntu.
But on my personnal laptop, I use Gentoo and I would like it to be
detected.
I have installed xsane and its dependencies (sane-backends, hplip,...)

When I launch xsane, it says it does not detect any device.
I launch it as user, I already added me to the scanner group.


# grep mihamina /etc/group
root::0:root,mihamina
disk::6:root,adm,mihamina
wheel::10:root,mihamina
audio::18:mihamina
cdrom::19:mihamina
cdrw::80:mihamina
portage::250:portage,root,mihamina
mihamina:x:1000:
scanner:!:1002:mihamina


I did not touch any of the files under /etc/sane.d/.
And last:


mihamina@asus ~ $ sane-find-scanner -q
found USB scanner (vendor=0x03f0 [Hewlett-Packard], 
product=0x0605 [HP ScanJet 2200C], chip=LM9832/3) at libusb:003:003
found USB scanner (vendor=0x05e1, product=0x0501) at libusb:001:003


The second found device is an embeded webcam. Nothing to do with a
scanner.
What should I do to make my scanner detected by xsane?

Thank you.

What are the results of running "scanimage --list-devices" both as root
and a normal user? Permission problems can cause scanimage or xsane to not
find the scanner while sane-find-scanner will.

As root:
	# scanimage --list-devices
	No scanners were identified. [...]
	# sane-find-scanner -q
	found USB scanner [...]
	found USB scanner [...]

As normal user:
	$ scanimage --list-devices
	No scanners were identified.
	$ sane-find-scanner -q
	found USB scanner [...]
	found USB scanner [...]

I know my scanner uses plustek driver, and I already
edited /etc/sane.d/plustek.conf, but I dont know how to exclude all
other configuration files so that they dont disturb mine...

PS: Sorry for the CCing, just to up the thread.

I don't have much experience with USB devices or how udev handles
them in /dev.  All my experience which is quite limited would suggest
that it is still a permission issue.  You could find the (ephemeral)
device file(s) and check the perms on them and then issue the groups
command to check against.  My guess is you still have a permission
problem that is more likely due to /etc/groups than to /etc/udev.d.

you may have to relogin as your user to apply the new group settings;
you may also have to be in the USB group; you may also have to unplug
and replug the scanner once after you add yourself to those groups.  

Just to be clear, I use Xsane and an HP Scanjet, i think 4300 C,
something close to that, and permission issues like this don't effect
root, so that would be agood way to test.

OK, so it's not a permissions issue. What shows up in your syslog when
you connect the scannner?

If you use syslog-ng, run "tail -f /var/log/message" then connect the
scanner.

Don't apologise, if you know it's wrong, don't do it. Not only do I get
two copies of your mail, but of every response when someone uses Reply to

here's the output from the system log, i use metalog so
that's /var/log/everything/current.

That's it? There would normally be several lines after that showing the
device's identification.

perhaps in another log somewhere, but i use the niash drivers and they
don't have configuration options, they might be a little quieter than
yours.

That's the way some mailing lists work because it's more 'RFC compliant'
and stuff.

I'd like to hear what RFC that suggests CCing the author of the email by 
default, please.

From what I understand the recommended default reply behavior is to reply 
to only the "Reply-To" or, if that header is absent, "From" 
header.  "Reply to all" to a feature that all MUAs should have, but it's 
used more often with large multiple TO+CC addresses rather than on lists.
