[sane-devel] fujitus scansnap ix500 (not found by sane-find-scanner)

2014-05-19 Thread andreo73 
Hi,
I'm trying to get a ix500 work on my pc with ubuntu 14.04 freshly installed;
the scanner is attached through usb cable to a usb2 port (my pc has only
usb2 ports)

when the usb cable is first connected (or the scanner is switched on), dmesg
reports

 usb 2-6: new high-speed USB device number 6 using ehci-pci
 usb 2-6: New USB device found, idVendor=04c5, idProduct=132b
 usb 2-6: New USB device strings: Mfr=1, Product=2, SerialNumber=0
 usb 2-6: Product: ScanSnap iX500
 usb 2-6: Manufacturer: Fujitsu

the backend is installed from the debian libsane package (version number
1.0.23-3ubuntu3)

I've modified the fujitsu.conf file appending at the end

#ScanSnap iX500
usb 0x04c5 0x132b

I've also modified /etc/default/saned to have RUN=yes  and restarted with
sudo service saned restart 
(the service starts with no errors)

sane-find-scanner *does not* find anything, even with sudo

sudo scanimage -L remains silend for almost a minute, during which the
scanner's blue light change status, becomes half/orange and flashing ; after
a minute or more, the response is No scanners were identified. 

any suggestion? where to start?

thanks!!

Dear allan, thanks for the quick reply

following your advice, I've installed 1.0.24 (after installing libusb-dev
package, I've followed standard procedure: ./configure, make and sudo make
install, now executables are under /usr/local/bin )

now sane-find-scanner works

 /usr/local/bin/sane-find-scanner

found USB scanner (vendor=0x04c5, product=0x132b) at libusb:002:007

-

and with sudo it works even better:

 sudo /usr/local/bin/sane-find-scanner

found USB scanner (vendor=0x04c5 [Fujitsu], product=0x132b [ScanSnap iX500])
at libusb:002:007

however sadly

 sudo /usr/local/bin/scanimage -L

No scanners were identified. If you  (etc. etc.)

again the scanner remains stuck with a yellow flashing half-light

any suggestion? I am concerned about the message received when the scanner
is powered on (from dmesg):

usb 2-6: new high-speed USB device number 7 using ehci-pci

is it normal ehci-pci?? 

any help is really welcome

thanks

 Andrea

ouch! you're so right

 SANE_DEBUG_FUJITSU=5 scanimage -L

[sanei_debug] Setting debug level of fujitsu to 5.
[fujitsu] sane_init: fujitsu backend 1.0.111, from sane-backends 1.0.23
[fujitsu] sane_get_devices: config option buffer-size (262144) is  65536,
warning!


I don't understand, how can it be? did it link to the wrong libraries during
compilation? how can I get the correct link?

Re: [sane-devel] fujitus scansnap ix500 (not found by sane-find-scanner)

2014-05-20 Thread andreo73 
Thanks!! Before changing /etc/ld.so.conf I try simplest methods, e.g. 

1) change name of /usr/lib/sane to /usr/lib/sane_OLDVERSION hoping that it
is sufficient to remove them from dynamical linking, but it did'nt work
(wonder why...)

2) prepend LD_LIBRARY_PATH=/usr/local/lib to the executable; this worked but
only with sudo

 LD_LIBRARY_PATH=/usr/local/lib SANE_DEBUG_FUJITSU=5 scanimage -L

[sanei_debug] Setting debug level of fujitsu to 5.
[fujitsu] sane_init: fujitsu backend 1.0.117, from sane-backends 1.0.24
[fujitsu] sane_get_devices: config option buffer-size (262144) is  65536,
warning!
[fujitsu] connect_fd: could not open device: 11

No scanners were identified. (etc.)

or otherwise with sudo:

 sudo LD_LIBRARY_PATH=/usr/local/lib SANE_DEBUG_FUJITSU=5 scanimage -L

[sanei_debug] Setting debug level of fujitsu to 5.
[fujitsu] sane_init: fujitsu backend 1.0.117, from sane-backends 1.0.24
[fujitsu] sane_get_devices: config option buffer-size (262144) is  65536,
warning!
device `fujitsu:ScanSnap iX500:55189' is a FUJITSU ScanSnap iX500 scanner



in conclusion now with

 sudo LD_LIBRARY_PATH=/usr/local/lib simple-scan 

I can get pages scanned!!

Hints (or reference) on how to fix the permission problem?

thanks a lot for the fast and precise help

Andrea

Re: [sane-devel] fujitus scansnap ix500 (not found by sane-find-scanner)

2014-05-20 Thread andreo73 
Ok, for the record (maybe useful for other people), in ubuntu udev is
controlling usb devices mounting

I've created the new file

/etc/udev/rules.d/40_fujitsu_scanner.rules

which contains the line

SUBSYSTEM==usb, ENV{DEVTYPE}==usb_device, ATTR{idVendor}==04c5,
ATTR{idProduct}==132b, MODE:=666

and now, whenever I switch on the scanner, the device is created with the
right permissions, no more need of sudo

thanks again

 Andrea
