[gentoo-user] Scanner Trouble

[gentoo-user] Scanner Trouble

[C. Beamer]

Hi,

When I first installed Gentoo on my main machine about a month ago, my
scanner was working just fine.  I don't use it that much, but today when
I went to use it (using xsane), I got a message that no devices were found.

I checked dmesg and as far as I can tell, there doesn't seem to be
anything wrong.

The only thing that I did that might have affected it (although it
doesn't seem to have affected anything else) is:

emerge --update --deep mozilla-firefox  (because there was an updated
Firefox package)

When I did this, emerge updated 26 packages including some x packages,
so I don't know if this is what is causing the problem.

The scanner works in Window - I tested it to be sure that it wasn't a
scanner problem.

Additionally, I used to have this problem when I ran FC4 all the time. 
I have a USB printer, zip drive and game pad all connected to my system
and all work fine.  The scanner is USB as well and in FC4, I used to
always have to remove the usb cable and plug it back in again and then I
could get xsane to recognize the scanner.  However, I tried that and had
no luck.

Any ideas?

Regards,

Colleen

Start at the beginning :-)

what is the output of 

lsusb

If you run 

watch --interval=1 lsusb

can you see the scanner being plugged and unplugged

(you may need to run these commands as root)

Have you checked your /etc/sane.d/dll.conf to make sure that the backend
that you need is not commented out by a rogue update?

what is the output of

scanimage -L

and

sane-find-scanner

can root use the scanner? What are the permissions on the scanner
device? (I assume that the user wanting to use it has to be in the
scanner group? sane-backends makes the scanner group so I assume thats
what it is for.)

what modules get loaded for the scanner? (lsmod)

Hi all,

I honestly don't know what I did.  I was playing around checking
different settings and now xsane works fine.

Sorry for the bother.

Colleen
