plustek: Thread: Problems with Epson 1250

I got my Epson 1250 to work on my Mandrake 8.2 just a few times. With
Sane 1.0.7 (from Mdk 8.2) I got bad colors. After upgrading to Sane
1.0.8, I got correct colors.

But most of the time, I can't get the scanner to work with Sane,
although it works with VueScan. sane-find-scanner finds my scanner, but
scanimage finds nothing. In my syslog I get the message "scanner.c:
open_scanner(0): Scanner device is already open/".

/Does anyone know what is wrong?

Thanks,
JJJ/

I had a similar problem as well. As it turns out you will probably have 2
sets of SANE libraries in you machine. The old one has to be deleted. I used
the "locate" app to find the libraries (look for "sane") and got rid of the
old ones... and it worked fine after that...

I upgraded via RPMs, so I guess this process should have removed the old 
libraries. I did check anyway, and I didn't find any old libraries around.

So does anyone have another idea what the problem may come from?

Couple questions:

1) does your kernel's drivers/usb/scanner.h have the vendor/product 
defines in it, or are they defined in /etc/modules.conf?  
Personally I've been doing the former by editing the file before I 
bult the kernel, but now its incorporated since about 2..4.19.
Presently running 2.4.20-pre7-ac3...

2) did the rpms change the perms on /dev/usb/scanner, or 
/dev/usbscanner?  I just took a quick look at my /dev/usb/scanner* 
stuff, and its all restricted to root, "crw------", so I'd expect 
to have to modify that to use it as non-root.  Yeah, a quick su 
gene and its "no devices found".

I have the vendor info as options in my modules.conf, since it is an 
Epson using the Plustek driver.

I had the same problems before I upgraded. Anyway, my /dev/usb/scanner0 
file is created on the fly when the scanner is plugged in, and the 
permissions seem to be assigned dynamically: the owner is the user 
logged in under X...

As I said below, everything seems to be set up correctly driver-wise, 
since I can scan perfectly using VueScan (commercial software, but cheap 
and mighty interesting). It's just Sane that seems to react strange with 
this "device already open" message.

I take it your are using the devfs system then?  I hadn't braved 
that bit of rather choppy water since it couldn't find the hard 
drive after mounting it during the bootup.  Made for an interesting 
recovery as I had to drop back about 3 kernel versions on the grub 
screen before it would reboot.

I've done that (reboot) too since I last emailed about this, and on 
the reboot, when I checked the perms on /dev/usb/scanner* it still 
came back as crw------, but with gene:root as owner:group, whereas 
whe n I looked yesterday I could have sworn it said root:root 
straight across the board for all 16 devices.  Snilmerg?

In any event, I'm fresh out of ideas with those 2 questions, anybody 
else have any ideas here?
