[sane-devel] ScanSnap 1300i: Error during device I/O

[Laurent Charrière]

Hi,

Gavin Carr at http://www.openfusion.net/linux/scansnap_1300i reports 
that he was able to get his Fujitsu ScanSnap 1300i ADF scanner to work 
with SANE on Centos 6.

I tried to do the same things he did (update /etc/sane.d/epjitsu.conf, 
add a udev rule) on Fedora 20 and 21, but I'm running into an "Error 
during device I/O":

* sane-find-scanners finds the scanner
found USB scanner (vendor=0x04c5 [FUJITSU], product=0x128d [ScanSnap 
S1300i]) at libusb:002:003

* scanimage -L sees it:
device `epjitsu:libusb:002:003' is a FUJITSU ScanSnap S1300i scanner

* scanimage -d epjitsu:libusb:002:003 --format=tiff >image.tiff
scanimage: sane_start: Error during device I/O

(If the sheet is not engaged in the ADF, the above command causes the 
scanner to start feeding it, as it does on a Mac).

* Trying to use the Centos 6 binaries and libraries on Fedora 20 yields 
the same I/O error on Fedora 20. On Fedora 21, I get scanimage: open of 
device epjitsu:libusb:002:003 failed: Invalid argument.

Setting SANE_DEBUG_FUJITSU to 35 and SANE_DEBUG_SANEI_USB to 128, the 
following is the last few lines of the output I get:
[sanei_usb] 000 1B D2                                           ..

dmesg says the following about the scanner:
[ 3775.121145] usb 2-1.1: new high-speed USB device number 3 using ehci-pci
[ 3775.209209] usb 2-1.1: New USB device found, idVendor=04c5, 
idProduct=128d
[ 3775.209214] usb 2-1.1: New USB device strings: Mfr=1, Product=2, 
SerialNumber=0
[ 3775.209217] usb 2-1.1: Product: ScanSnap S1300i
[ 3775.209220] usb 2-1.1: Manufacturer: FUJITSU

(I'm including the dmesg snippet because Gavin's dmesg reports that the 
device is using ehci_hcd).

The device is connected to a Lenovo Thinkpad T410. I tried two different 
USB ports with the same result. The device works fine when connected to 
a Mac. The Thinkpad USB ports work fine otherwise.

Does anybody have any suggestions as to the next steps I can take to 
investigate this?

Thanks,

Laurent
