Canon LiDE 70 support

Hi,

I'm newly subscribed here, and found just two postings about
this
scanner in the archives. I purchased one today and am trying
to get
support for it. So far, no success. I tried to just add a
struct
canon_lide_70_model into genesys_devices.c by copying the
lide_60 part
and only adjusting the resolutions and model names, and
adding a line
  {0x04a9, 0x221c, &canon_lide_60_model},
into genesys_usb_device_list. After this, I added the usb
data to
/etc/sane.d/genesys.conf, and then after compiling I get:

# scanimage -L
device `genesys:libusb:004:007' is a Canon LiDE 70 flatbed
scanner

but scanning doesn't actually work:

# scanimage > ~/file.pnm
scanimage: open of device genesys:libusb:004:007 failed:
Invalid argument

The scanner doesn't show any reaction. I wonder if it's a
GENE based one
at all. How do I find out?  How can I help to get this
supported? I have
14 days before I have to send it back if it doesn't work...

I'm using gentoo Linux 2.6.17-r8 and sane-backends
1.0.18-r2.

Here is the lsusb -v -v output's section about the scanner:
