scanner not working after upgrade to Dapper

[ainsaur]

My Epson 3170 scanner was working fine before my upgrade to Dapper. It now won't work. I had reinstalled the iscan and iscan plugin files from epkowa. When I do sane-find-scanner, it finds it on libusb:003:002. However, scanimage doesn't see the scanner. Any ideas?

Re: scanner not working after upgrade to Dapper

Had you recently powered up your scanner? I find mine shows up in sane-find-scanner a few minutes (!) before it'll actually work. (Of course, I use it infrequently enough that I forget, and get all confused about why it's not working...).

Another thing you could check is if /proc/bus/usb/003/002 is read/writable by your user. (sudo chown <your username> /proc/bus/usb/003/002 if not)

Re: scanner not working after upgrade to Dapper

Strange...I did another sane-find-scanner and I got this...

found USB scanner (vendor=0x04b8, product=0x0116) at libusb:006:003

I didn't touch anything so why am I getting a different result?

Re: scanner not working after upgrade to Dapper

Well, the first number is the bus number. I'd expect this to stay constant if the device is plugged into the same USB port on your computer. The second number is the device number, which is likely to change as it's allocated sequentially, but can be reused (ie. the first device plugged in is 001, next is 002, but if you unplug that and plug another in, it might be 003 or 002, depending on whether the kernel decides to reuse the number or not. Also note that bumping the power cable to powered USB devices can be the same as unplugging it, so sometimes that can cause the device number to be reallocated...)

As far as I can see, there's no entry for your scanner in the default dapper udev rules, so you might want to add one so that it automatically gets the right permissions when it's detected.

I recommend adding a new file to /etc/udev (rather than editing an existing one; this way it won't get lost in an update):
sudo kate /etc/udev/99-epsonscanner.rules

Add these two lines (sorry, the second one probably wraps):
# Epson Corp.|Perfection 3170
SYSFS{idVendor}=="04b8", SYSFS{idProduct}=="0116", MODE="664", GROUP="scanner"

and save it. Now when you plug it in next it'll have the right permissions. You may still need to tell your scanning program to rescan to find it each time, but you'll save yourself the chmod step.

(You can file a bug against libsane to suggest they add those lines to the 45-libsane.rules file.)

Re: scanner not working after upgrade to Dapper

I gave it a try but I'm still getting the "cannot send command to scanner" error and scanimage still reports that there are no scanners attached. Perhaps I don't have the right files installed. I don't know if I need all of these but this is what I have:

sane
libsane
sane-utils
iscan
iscan-plugin-gt

I've also edited the epkowa.conf file to include "usb 0x04b8 0x0116. Am I missing something here?

Re: scanner not working after upgrade to Dapper

I have some other information. First, I did a clean install from the CD. I don't know if that information helps but I figure that the install reset a file that I previously had modified. Another bit of information is that when I try to start iscan from the console, I get this output:

alex@Kubuntu:~$ iscan
X Error: BadDevice, invalid or uninitialized input device 168
Major opcode: 145
Minor opcode: 3
Resource id: 0x0
Failed to open device
X Error: BadDevice, invalid or uninitialized input device 168
Major opcode: 145
Minor opcode: 3
Resource id: 0x0
Failed to open device

I hope that someone has other suggestions for me because this is getting pretty frustrating!

Re: scanner not working after upgrade to Dapper

Don't worry about those messages (See this post: http://kubuntuforums.net/forums/index.php?topic=5772.0 ).

What would be useful is the output of these commands:
dmesg
sane-find-scanner
ls -l /proc/bus/usb/003/002 (or wherever sane-find-scanner says your scanner is)
groups

Okay, here is the output for each command:

Re: scanner not working after upgrade to Dapper

Seems you still don't have the right permissions on the file in /proc. You can do:
sudo chgrp scanner /proc/bus/usb/003/002
sudo chmod 664 /proc/bus/usb/003/002

but I thought that udev rules file mod should have done this automatically. (This way you'll need to issue those two commands after every reboot.)

[ainsaur]

Re: scanner not working after upgrade to Dapper

I tried the commands and I got a strange result. After changing permissions, I tried "iscan" but I got the same result (cannot send command to scanner). I tried "sudo iscan" and nothing happened (not even the "cannot send..." error) for about 30 seconds. I closed the session and then "iscan" ran. However, my scanner didn't start up. When I clicked on the preview button, I then got the "cannot send command..." error message.

Here is the output from sane-find-scanner:

found USB scanner (vendor=0x04b8, product=0x0116) at libusb:003:002

Here is the output from ls -l /proc/bus/usb/003/002

Re: scanner not working after upgrade to Dapper

I'm afraid I can't help with iscan stuff, since I don't use that. (Personally, I use kooka from the kdegraphics, and that's on a non-ubuntu machine too for now.)

The permissions look right, since you can read/write that file since you're in the scanner group, so it's a mystery to me why iscan doesn't think it can send the command.

[ainsaur]

Re: scanner not working after upgrade to Dapper


Do you know why I'm having trouble with "sudo iscan"? I expected to be asked for a password and then have the program start. Instead, it only seemed to start after I close the session. Also, are there other configuration files that I should I look at?

[marble]

Re: scanner not working after upgrade to Dapper

That is strange. sudo sometimes doesn't ask for a password if you've recently successfully sudo'd something, but I can see no reason it would wait for the session to be closed. Maybe it's slow to start up? I expect it downloads firmware to the scanner on startup.

For me (note that I have an Epson Perfection 2480, and this is from a non-ubuntu system), I have edited /etc/sane.d/snapscan.conf to include the line:
firmware /etc/sane.d/esfw41.bin
and I put the downloaded esfw41.bin (firmware file) into /etc/sane.d

I can't find your Epson 3170 on sane-project.org, so I don't know if yours is snapscan based too.

[ainsaur]

Re: scanner not working after upgrade to Dapper

I'm not sure what is going on either. Iscan generally loads up in a few seconds so I don't think that it is loading too slowly. Is there anything else I can check to make sure that I have the proper permissions?

[ainsaur]

Re: scanner not working after upgrade to Dapper

I found out some more information. It seems that I don't have a scanner module installed. Here is the output from lsmod:

I then tried modprobe... and I got this:

How can I find/install the scanner module?
