Cheers. I'm a sane/xsane newbie with a problem. Any
|
|
<BR>
|
|
advice/solutions/things to try will be welcomed.
|
|
<BR>
|
|
<P>Thanks,

<P><P>The problem
|
|
<BR>
|
|
-----------
|
|
<BR>
|
|
scanimage works fine (great, in fact), but xscanimage and xsane both claim
|
|
<BR>
|
|
that the scanner is busy.
|
|
<BR>
|
|
<P><P>The environment
|
|

$ scanimage -L

device `epson:/dev/usbscanner' is a Epson Perfection1240 flatbed scanner
|
|
<BR>
|
|
<P>$ scanimage --format=tiff >image.tiff

(no problems)

(dialog says "Failed to open device `epson:/dev/usbscanner': Device busy."

just like xscan image)

------------------------------

|
|
* I've verified that there are no other versions of sane or xsane around
|
|
<BR>
|
|
<P>* I've pored over READMEs, FAQs, etc.
|
|
<BR>
|
|
<P>* DEBUG flags:

<BR>
|
|
^^^^^^^^^^^^^^^^^^^^^
|
|
<BR>
|
|
Hmm, that's suspicious. Is that trying to open a filed called
|
|
<BR>
|
|
`epson:/dev/usbscanner'?
|
|
<BR>
|
|
<P><P>* strace:
|
|
<BR>
|
|
$ ( strace /usr/local/bin/xsane epson:/dev/usbscanner ) >log 2>&1
|
|
<BR>
|
|
And log says:
|
|
<BR>
|
|
execve("/usr/local/bin/xsane", ["/usr/local/bin/xsane", "epson:/dev/usbscanner"], [/* 72 vars */]) = 0
|
|
<BR>
|
|
[snip]
|
|
<BR>
|
|
open("epson:/dev/usbscanner", O_RDWR) = -1 ENOENT (No such file or directory)
|
|
<BR>
|
|
^^^^^^^^^^^^^^^^^^^^^
|
|
<BR>
|
|
Indeed, it's trying to open this literally.
|
|
<BR>
|
|
(As a trick, I tried symlinking `./epson:usbscanner' to this, but no luck)
