Hi,

I noticed that 2.6.2-mm1, usb scanner is removed. With
vanilla 2.6.2, this modules always OOP and somebody
said we should use libusb instead. However after
googling for a while I can not find any documentation
how to use that even in the libusb homepage. Please
help me , or pinpoint some place I could have some
guides. Thank
you.

Some distros ship it.
home page is http://libusb.sourceforge.net/

Use it with xsane for scanning.

Get the latest version of xsane and use it.  It should have the libusb
support built into it already.

If you have any problems, try asking on the xsane mailing lists.

Good luck,

Yes it saved me. It work now. Why no other sane
documentation said like yours? I think people at sane
project should take your point to add to their
documentation.

I dont use rpm based system, I use my own built linux
system half based on slackware 9.0 so your information
is really helpful. Before I got stuck. Run
sane-find-scanner, it said find usb scanner, but when
run scanimage -L it always tell me only bttv device
available!. Even I feed it with --device
libusb:XXX:XXX (from sane-find-scanner output) and it
still refuses, Invalid argument message. Hm until
now...

Thank you again.

Can I plead alzheimers or something?  Working with ancient grey matter 
here.  Its working on the 70th trip around our star. :-)

I don't ATM recall exactly where I first heard or read about this.

Maybe in the libusb docs?  No, not a thing, even clear back up to the 
root dir of the libusb archive.  Maybe I got it from the sane list?

In any event, thats too damned hard to find and if the libusb author 
is copying the mail here, that little detail really should be added 
to the README and/or INSTALL.libusb raw text files, or to a FAQ on 
the libusb website, the quicker of the two alternatives if this 
version of the library is stable (and it seems so to me).

The authors doc/html files are quite complete, I just read them all, 
but they attack *only* the api the programmer would use, and the 
actual non-programming user who just wants to use his scanner with 
this new-fangled system gets hung out to dry.  This question gets 
asked, and answered the same way, many times on the sane list too.

It may have been added to the sane-backend docs in a recent version, 
I'm at least one version out of date here, not being inclined to "fix 
something thats not broken" at my home site. :-)

Thank you so much for the tip!  This seems to have solved my problem
too.

I changed my epson.conf file to just say
"usb"
instead of
"usb /dev/usb/scanner0"

and now, finally, it works.  I do hope the SANE documentation writers
get around to adding that little tidbit of info SOMEWHERE,  I was
tearing my hair out and rebooting back to 2.4 to use my scanner.  

Also, now that usb-scanner.ko is gone, a paragraph of help in the 
http://www.codemonkey.org.uk/docs/post-halloween-2.6.txt
file would be a great thing as well.

I tried that in 2.6.5-rc1-mm1, restarted sane, but it still fails. 
scanimage -L does not find the scanner, sane-find-scanner finds it, but 
says I have scsi modules loaded, even though I've rmmod them. I'm using 
a recent CVS libusb and sane.
I found an article on linuxtoday.com that pointed me to vuescan where I 
downloaded their initial linux release and the scanner (Epson USB 610) 
works fine using it. It uses the libusb-0.1.so.4.4.1 I have installed, 
so that points back to a problem with sane which I have added to their 
bug list.
Regards
Sid.
