Hi,
|
|
<BR>
|
|
<P>this all sounds a bit strange to me...
|
|
<BR>
|
|
<P><EM>> First thing I noticed was that scanimage was no longer in the path, and
|
|
</EM><BR>
|
|
<EM>> xscanimage was no longer available at all. So, I cd /usr/local/bin and type
|
|
</EM><BR>
|
|
<EM>> ./scanimage -L. Lo and behold, I see on the screen something to the effect:
|
|
</EM><BR>
|
|
<EM>> "Device snapscan:/dev/usbscanner is a Color FlatbedScanner13 flatbed
|
|
</EM><BR>
|
|
<EM>> scanner" or something like that.
|
|
</EM><BR>
|
|
<P>This seems to indicate two things: Your PATH may not include /usr/local/bin or
|
|
<BR>
|
|
you haven't 'rehashed' after uninstalling and installing sane. This should be
|
|
<BR>
|
|
easy to resolve. Secondly, USB communication seems to work, otherwise scanimage
|
|
<BR>
|
|
wouldn't recognize your scanner.
|
|
<BR>
|
|
<P><EM>> 2) Unfortunately, when I run ./scanimage -T the system essentially core
|
|
</EM><BR>
|
|
<EM>> dumps (not a core dump but something like it).
|
|
</EM><BR>
|
|
|
|
<BR>
|
|
<EM>> 3) According to the original instructions as well as info here I'm supposed
|
|
</EM><BR>
|
|
<EM>> to upload new firmware using the acerfirm utility. I have been trying to do
|
|
</EM><BR>
|
|
<EM>> this from the very beginning but something has changed and I don't know
|
|
</EM><BR>
|
|
<EM>> what. Originally I could simply type ./acerfirm -v /dev/usbscanner
|
|
</EM><BR>
|
|
<EM>> u64v115.bin and I would see the intial scanner read info (scanner would show
|
|
</EM><BR>
|
|
<EM>> as a FlatbedScanner16 with a firmware date of Oct. 1999). Within a few
|
|
</EM><BR>
|
|
<EM>> moments, the scanner would make all sorts of good noise (reinitializing) and
|
|
</EM><BR>
|
|
<EM>> then acerfirm would report that the firmware was successfully uploaded.
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> Now, however, no matter when I attempt to run that same utility, I
|
|
</EM><BR>
|
|
<EM>> constantly get "scanner.c read.scanner got funky result: -75. contact
|
|
</EM><BR>
|
|
<EM>> maintainer (again, may not be exact but the funky result: -75 is)". The
|
|
</EM><BR>
|
|
<EM>> scanner makes no noise, and this time the info returned from the scanner is
|
|
</EM><BR>
|
|
<EM>> blank.
|
|
</EM><BR>
|
|
<P>This again sounds as if USB communication does not work anymore. First,
|
|
<BR>
|
|
'acerfirm' is independent of sane, so it should work no matter how you compiled
|
|
<BR>
|
|
and installed sane. If it doesn't work there is probably something wrong with
|
|
<BR>
|
|
the USB kernel layer (scanner.c is part of the kernel USB layer). The best
|
|
<BR>
|
|
thing I can suggest is a reboot or unloading and reloading of all USB related
|
|
<BR>
|
|
kernel modules (scanner, usb-uhci or usb-ohci and usbcore). Be sure that the
|
|
<BR>
|
|
scanner module recognizes your scanner (you should get something similar to the
|
|
<BR>
|
|
dump below in /var/log/messages:
|
|
<BR>
|
|
<P>scanner.c: USB Scanner support registered.
|
|
<BR>
|
|
scanner.c: open_scanner(0): invalid scn_minor
|
|
<BR>
|
|
usb.c: USB new device connect, assigned device number 2
|
|
<BR>
|
|
scanner.c: probe_scanner: User specified USB scanner -- Vendor:Product -
|
|
<BR>
|
|
4a5:2040
|
|
<BR>
|
|
<P>You may have to supply the vendor and product ID by hand to the scanner module
|
|
<BR>
|
|
- the version I have doesn't recognize my scanner automatically.
|
|
<BR>
|
|
<P><EM>> There must be something installed incorrectly. I edited
|
|
</EM><BR>
|
|
<EM>> /usr/local/etc/sane.d/sane.conf to add Color and /dev/usbscanner. There is
|
|
</EM><BR>
|
|
<EM>> also an /etc/sane.d directory which contained sane.conf.rpmsave. Is it
|
|
</EM><BR>
|
|
<EM>> possible that the rpm created the /etc/sane.d directory? Should I symlink
|
|
</EM><BR>
|
|
<EM>> this to /usr/local/etc/sane.d?
|
|
</EM><BR>
|
|
<P>Obviously the previous installation used /etc/sane.d. You have modified
|
|
<BR>
|
|
sane.conf, so rpm didn't delete the file and directory. You can probably delete
|
|
<BR>
|
|
the whole stuff manually, but it doesn't hurt if it's still there.
|
|
<BR>
|
|
<P>Still, the problem remains that USB communication in (1) worked and later it
|
|
<BR>
|
|
didn't. The only solution I can think of is that you have loaded kernel modules
|
|
<BR>
|
|
with different parameters between both tests.
|
|
<BR>
|
|
<P>You should first try to get acerfirm to work again. Once you have uploaded the
|
|
<BR>
|
|
firmware 'scanimage -L' should report 'FlatbedScanner16' instead of
|
|
<BR>
|
|
'FlatbedScanner13'. (You won't be able to scan at all with the original
|
|
<BR>
|
|
firmware).
|
|
<BR>
|
|
<P>If scanimage still coredumps you should supply the output. Maybe it makes sense
|
|
<BR>
|
|
to someone.
|
|
<BR>
|
|
<P>Good luck,
|
|
<BR>
|
|
<P>Oliver
|
|
<BR>
