it'll (hopefully produce a line like this:

found USB scanner (vendor=0x04a9, product=0x220e, chip=LM983x?) at
libusb:001:00 2

if run as a regular user, or like this

found USB scanner (vendor=0x04a9 [Canon], product=0x220e [CanoScan],
chip=LM9832/3) at libusb:001:002

if run as root.

these both indicate a scanner at /proc/bus/usb/001/002

I'm scanning ok as root, but having a bit of trouble letting normal
users scan...  See also the manpage for sane-usb.

Thanks for the tip and suggestion(s)..

Here is what I see when I run 'same-find-scanner'  as root:

"found USB scanner (vendor=0x03f0, product=0x2005) at libusb:001:002
  # Your USB scanner was (probably) detected. It may or may not be
supported by
  # SANE. Try scanimage -L and read the backend's manpage."

However, I don't get much when I run 'scanimage -L'.

But I do have an indication that a scanner exists at -
/proc/bus/usb/001/002"

Don't know if any of this is good or bad news..

As root, execute

chmod a+w /proc/bus/usb/001/002

Unfortunately, until a bug is fixed, you will have to do this each time 
you reboot.  Note the digits are specific to your system as determined 
by executing scanimage as you did.

Hope this gets it working.

I've only just started to try to get sane working for my scanner.

I started with man sane... Eventually I found out about the vendor file
required for my scanner. Then With the exceptions {listed below}, root
could scan...

Now thanks to your advice to Ted, I can now scan as user... Because of the
bug you mentioned I just put a script in /root/bin/fixscan that consists of a
single chmod command... Works for me! Thanks.

Note: due to the exceptions {listed below} which now also applied to my
user login, I kept reading the man docs, I found in man sane-usb a
reference to an /etc/fstab line that was supposed to let ALL users
access the scanner...

"none /proc/bus/usb usbfs defaults,devmode=0666  0  0"

This didn't work! presumably thats because of the bug you mentioned?

OK the exceptions: [assume inches]

I was using a test page that consisted of an 8 1/2 x 11 glossy sheet
with some hand writing above and below a printed photo that took up
about 1/2 the sheet of paper.

With:
scanimage --format tiff >tst.tiff

I got a tiff file with a picture of the the top left corner (aprox 2 x 2)
of the sheet.

With xsane I get the same image scan area.

Yet kooka gives me the whole 8 1/2 x 11 page.

I think I like kooka better than the windows scan panel Memorex thinks
I'm using, so that parts good. (Except for an error message I don't
understand)  But I'd like to be able to scan from the command line...

Below is pasted some konole output that may mean more to you than to me.

How would I get scanimage and/or xsane to scan the whole page?

..or, switch on the scanner after you log in, not before, in which
case this should be done automatically.
