[sane-devel] "Error during device I/O" with Fujitsu fi65-F (epjitsu backend)

Hi,
The Fujitsu fi65-F has recently showed up on the supported device list for the epjitsu backend, but I'm struggling to get it to scan an image using Ubuntu 14.04. Below are all the details but the gist is:
* sane-find-scanner finds the scanner
* scanimage -L recognizes the scanner
* scanimage makes the scanner move back and forth (homing?) a little but then prints "scanimage: output is not a file, exiting"
* repeated use of scanimage fails and prints "scanimage: no SANE devices found"
* scanimage -T shows similar behavior and prints "scanimage: sane_start: Error during device I/O"
* I'm using the latest sane-backends from the Git repo
Did anyone else get this scanner working? Or maybe has seen similar behavior with a different device? This is my first time using SANE and I'm not quite sure if this is user error or not, and if it isn't what my next steps for debugging should be.
Below are my setup steps and outputs of scanimage with debug flags set.
Starting from a plain Ubuntu 14.04 box with basic tooling (gcc, vi, and so on), here are my setup steps:
sudo apt-get install libusb-dev
git clone git://git.debian.org/sane/sane-backends.git
cd sane-backends
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var BACKENDS="epjitsu"
make
sudo make install
# copy /usr/share/sane/epjitsu/65f_0000.nal extracted from Windows driver
echo "# Fujitsu fi-65F" >> /etc/sane.d/epjitsu.conf
echo "firmware /usr/share/sane/epjitsu/65f_0000.nal" >> /etc/sane.d/epjitsu.conf
echo "usb 0x04c5 0x11bd" >> /etc/sane.d/epjitsu.conf
# comment out everything but epjitsu in /etc/sane.d/dll.conf
sane-find-scanner:
jonas at sane-scanner:~$ sane-find-scanner
# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.
# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.
found USB scanner (vendor=0x04c5, product=0x11bd) at libusb:001:003
# Your USB scanner was (probably) detected. It may or may not be supported by
# SANE. Try scanimage -L and read the backend's manpage.
# Not checking for parallel port scanners.
# Most Scanners connected to the parallel port or other proprietary ports
# can't be detected by this program.
# You may want to run this program as root to find all devices. Once you
# found the scanner devices, be sure to adjust access permissions as
# necessary.
