[gentoo-amd64] USB scanners and udev

[gentoo-amd64] USB scanners and udev

[Peter Humphrey]

Also not, perhaps, a 64-bit problem, but can someone please confirm that 
they can plug a USB scanner in and have it work? I have an Epson Perfection 
640U which works under M$ but not Gentoo.

I'm trying to follow gentoo-wiki.com/HOWTO_Installing_USB_Scanner, although 
it's not easy with so many variations being covered in the one document. I 
get as far as:

# sane-find-scanner -q
found USB scanner (vendor=0x04b8 [EPSON], product=0x010c [Perfection640  ]) 
at libusb:002:007

...but:
# scanimage -L

No scanners were identified. [...]

I can locate the /dev/usbdev* devices that are created when I plug the 
scanner in; changing their ownership to root:scanner has no effect on 
scanimage. I am in the scanner group, but running as root makes no 
difference anyway.

Udev is at version 106, kernel 2.6.20, hotplug is started in the default 
run-level (though it seems to make no difference); what else can I say?

Do I have to write a udev rule? /lib64/modules/2.6.20-gentoo/modules.usbmap 
contains nothing pertaining to my scanner, or is this a red herring?

/proc/sys/kernel/hotplug contains a single blank line. Another red herring?

I have some ancient UMAX scanner working. I don't remember everything
that's necessary. I seem to have /etc/hotplug/usb/libusbscanner,
/etc/hotplug/usb/libsane.usermap, /etc/udev/rules.d/99-libsane.rules,
and /etc/udev/rules.d/92-scanner.rules. The last has just this in it:

BUS=="usb", SYSFS{idVendor}=="1606", SYSFS{idProduct}=="0230", GROUP="scanner", MODE="664"

I don't know whether I put that there or portage did.

Hmm. I'm missing that file. I'll add it and see what happens. What 
does "equery b /etc/udev/rules.d/92-scanner.rules" give on your box?

It didn't help.

You'll need the numbers for your scanner, presumably.

Good idea. Portage has no idea what it is, so I must have written it
myself.

Not solely a scanner, but my Brother MFC-6800 scans, and prints under
Gentoo, and it's attached via USB.  It requires a bit of playing
with /dev directory permissions to allow the normal user to use it
however.  FYI, I used Xsane, and followed the gentoo-wiki page.

I run both a 640u and a 1260 under Gentoo 64 bit (but I did install the 
libraries for 32bit compatibility, so maybe that plays a role).

I have all the emul-linux packages installed except for java, medialibs and 
sdl. I can't imagine that any of those is causing this problem.

In answer to Barry, I have this:

$ cat /etc/udev/rules.d/92-scanner.rules
BUS=="usb", SYSFS{idVendor}=="0x4b8", SYSFS{idProduct}=="0x106", 
GROUP="scanner", MODE="660"

Those numbers are I believe correct for my scanner.

In reply to Antoine, after removing all other entries 
from /etc/sane.d/epson.conf I get these log entries when I plug the scanner 
in:

So the scanner evidently is being detected and recognised, but I still get 
no-scanners from scanimage -L.

Maybe the scanner is faulty, but it does work for M$.

The strange thing is that I don't have any scanner.rules in my /etc/udev/,
neither on Gentoo /with the Epson 1260) nor on Mepis (Ubuntu based) that uses 
the 640u at the moment.

Maybe I'm not using udev for the scanner? I do have a libsane.rules in Mepis, 
in Gentoo I only have udev-early, udev, fuse and vmware rules

I only created that file during this investigation, following a suggestion 
by Barry.

Hmm. Perhaps I should try another distribution to see how that goes. 
Meanwhile:

$ ls /etc/udev/rules.d
05-udev-early.rules          60-vmware.rules                
75-persistent-net-generator.rules  99-libsane.rules
50-udev.rules                70-persistent-cd.rules         92-scanner.rules
60-persistent-input.rules    70-persistent-net.rules        95-net.rules
60-persistent-storage.rules  75-cd-aliases-generator.rules  
99-libgphoto2.rules

Rather more than your system, it seems!

Barry, maybe I should look for a more amenable scanner? This one was only a 
basic one for my mother a few years ago (she's now 85 and on her second 
computer!). I've tried finding suggestions as to a suitable device, but not 
got anywhere yet. I'll try the local LUG next, I think.

Don’t get what I’ve got, it sucks! :)

I got mine when it was already obsolete because at the time I needed
SCSI to go with my obsolete computer, and this scanner just happened
also to have USB. Using it with SCSI now would be much messier, though
perhaps would work better. I was replacing another, earlier UMAX
scanner that sucked so powerfully that the computer room had no air
left in it.

On my system I have /etc/udev/rules.d/99-libsane.rules which belongs to 
media-gfx/sane-backends-1.0.18-r2.

I emerged xsane, sane-backends and sane-frontends and except for adding 
myself to the scanner group it "just worked". I have an Epson 1650 scanner.
I don't use it much.

Perhaps re-emerging the sane packages would clean things up.

I also have 99-libsane.rules owned by media-gfx/sane-backends-1.0.18-r2. This 
is the rules file which identifies the USB device as a scanner and sets the 
correct permissions so that is just works. Please try emerging it again and 
ensuring it is there.

Then run udevstart to apply the rules.

I too have the same file, but I've now removed 92-scanner.rules and the 
scanner is being detected. The significant change was to put 
SANE_BACKENDS="epson" into /etc/make.conf and then remerge sane-backends.

I may have missed that step before.

Thanks all for the help in getting this problem fixed.

It took me some labor to get my scanner working, and then, when things
inside Gentoo had changed and I tried to use the scanner, I found I
had to labor all over again. In fact I think I had more trouble the
second time.

Re: [gentoo-amd64] USB scanners and udev

[Antoine Martin]

I have used a Perfection 610 (usb) without problems for years with Linux 
  so it is unlikely to be a problem with udev/kernel.

Here is the line I have in /etc/sane.d/epson.conf:
usb 04b8 0103

This matches the usb id:
# lsusb  | grep Epson
Bus 001 Device 015: ID 04b8:0103 Seiko Epson Corp. Perfection 610

You should not need anything special (32-bit libraries, etc..)

Hope this helps
