sane-epjitsu backend stopped working with linux 3.6.2

I have been using a fujitsu scan snap 300m with arch linux for over three years. It has always worked fine.

With the upgrade to linux 3.6.2, scanimage can no longer find the scanner. When calling scanimage, I get the following error:

[20:14]% scanimage --device epjitsu > out.pnm
scanimage: open of device epjitsu failed: Invalid argument

Was there a regression with the new kernel and usb peripherals or udev permissions?

Here are the details:

All other usb devices (including usb stick automounting) are working correctly.

The scanner is attached:

[20:14]% lsusb

Bus 001 Device 005: ID 04f2:b071 Chicony Electronics Co., Ltd 2.0M UVC Webcam / CNF7129

Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

I have the firmware installed:

[20:13]% ls /usr/share/sane/epjitsu                      
300M_0B00.nal

/etc/sane.d/epjitsu.conf is correct:

# Fujitsu S300M
firmware /usr/share/sane/epjitsu/300M_0B00.nal
usb 0x04c5 0x117f

Permissions are correct in //lib/udev/rules.d/53-sane.rules     

# Fujitsu ScanSnap S300M
ATTRS{idVendor}=="04c5", ATTRS{idProduct}=="117f", MODE="0664",                 GROUP="scanner", ENV{libsane_matched}="yes"

Sane-find-scanner sees the scanner:

[20:15]% sane-find-scanner
[...]
found USB scanner (vendor=0x04c5 [FUJITSU], product=0x117f [ScanSnap S300M]) at libusb:001:006
  # Your USB scanner was (probably) detected. It may or may not be supported by
  # SANE. Try scanimage -L and read the backend's manpage.
[...]

I am a member of the group scanner:

[20:15]% groups                                                       
lp wheel network video audio storage scanner power users matt abs sbox

And here is what scanimage -L prints out:

[20:25]% scanimage -L
device `v4l:/dev/video0' is a Noname CNF7129 virtual device

Note running scanimage as root has the same result, so this does not seem to be a permissions issue.

What else am I missing?

For further reference, here's what udevadmin reports:

monitor will print the received events for:

So it looks like everything is being recognized. But neither "scanimage -L" nor "sudo scanimage -L" recognizes the device.

FWIW, the same problem has occurred with the scan snap S1300 on my arch linux box at work.

I can confirm, moreover, that I have no problem with linux-lts. So this is definitely a kernel issue. I suppose I'll scour the bug reports there.

I've got exactly the same problem with ScanSnap S300 and Linux 3.6.2.
