Epson 1250U usb scanner, latest sane can't find it.

Epson 1250U usb scanner, latest sane can't find it.

Post by Gene Hesket » Sun, 09 Dec 2001 14:18:06



Based on *sane* saying it supports usb scanners now, I bought one, an
Epson 1250U.

All I can get from dmesg is that its vernor/product codes aren't claimed
by any driver.

Based on the examples in linux-2.4.16-pre1/Doc*/usb/scanner.txt, I tried
to add those lines to modules.conf, but that gives an error on the
'modprobe scanner' line killing half the system which isn't good.
Interestingly, I can exec that exact same line from the a shell without
errors, and the scanner module is successfully loaded.  lsmod says its
there, with no linkages, but if I then try to rmmod it, its busy and
can't be removed.  Only a reboot removes scanner.o once loaded.

But there seems to be no way to give the 'options vendor=0x04b8
product=0x010f' to it from a shell.  No examples are shown in the man
pages...

I've been using a usb mouse for quite a while, great mouse, so that at
least is working.  uhci is compiled in, as is the mouse stuff, and
everything else in the usb menus of xconfig is set as a module.

Any hints on how to do this will be gleefully pursued.

Cheers, Gene

I am pretty sure that the 1250 is unsupported now and possibly in the
future. I guess it doesn't "speak" the same language as other supported
Epson scanners. The 1650 is supported by 'sane'. Check the 'sane'
homepage to verify what I have told you, in case I flubbed it.

I think you were misinformed.

Look at the list of supported USB scanners, here:

It says:

Take it back to the store.

Sounds like, thanks (even if I didn't want to hear that)
Thank heavens Staples and I get along pretty well.  I mean we (the tv
station 'we') do buy a lot of stuff from them.  :-)

Just becuase it says it supports "USB scanners" doesn't mean it supports
*this* USB scanner. You should check the SANE web site before making a
purchase decision for a Linux scanner. Many USB scanners are supported,
though.

Apparently, there are at least two types of "support".
Basic driver/language support which is built into sane. If your scanner
uses some new language or format you'd have to wait until the sane guys
provide support in the program.

However, unlike ftape(at least now) support for a specific scanner which
uses generic languages is built into the scanner module in linux.  In my
case the Epson 1240U was not supported by the kernel I was running and I
had to add the vender/device info to the scanner.c file in the kernel
tree and recompile.  There's a way to do it with modules but I wasn't
able to get that to work.  Ultimately I found that the 2.4.5 version of
linux came out of the box with the necessary code for that scanner even
though it was in a different place.

Regardless, when you get it working you'll be absolutely delighted.
