[sane-devel] Epson Perfection 3170 on 64 bit

[Ingo Müller]

Hey everyone!

I just realized that I've just spent 3 hours on trying to install my
Epson Perfection 3170, without success. Maybe you guys can help me...

Here's what I did:

1) Download iscan_2.10.0-1.tar.gz from
http://www.avasys.jp/lx-bin2/linux_e/scan/DL2.do

2) untar, configure --with-pic, make, checkinstall

3) Test -- scanner not found:

> ingo at ingo-e6400:~$ sane-find-scanner -q
> found USB scanner (vendor=0x04b8 [EPSON], product=0x0116 [EPSON Scanner]) at libusb:002:072
> 
> ingo at ingo-e6400:~$ sudo scanimage -L
> 
> No scanners were identified. If you were expecting something different,
> check that the scanner is plugged in, turned on and detected by the    
> sane-find-scanner tool (if appropriate). Please read the documentation 
> which came with this software (README, FAQ, manpages).                 

Some more tests, I performed:

> ingo at ingo-e6400:~$ ls /dev/ | grep scanner
> ingo at ingo-e6400:~$ ls /dev/ -1 | grep usb
> usbmon0
> usbmon1
> usbmon2
> usbmon3
> usbmon4
> usbmon5
> usbmon6
> usbmon7
> usbmon8

> scanimage: open of device epkowa:/dev/bus/usb/002/072 failed: Invalid argument

First observation: the device node is not created. Is that a problem?
How can I now why it is not created?

Then, scanimage doesn't find the scanner, neither does it want to work
with the device node under /dev/bus/usb/002/072. Am I doing this right?

Any further hints or ways I can obtain more information, why it's not
working? I'd really appriciate it!

Best regards,
Ingo
