Regarding the inability of vuescan 78 to recognize scanners uder Linux,
I guess we'll just have to wait for 79 and see if that version solves
the problem.

Hopefully, it will.

Vuescan .78 has no problem recognizing my scanner, Epson 2450,
Debian Sid, Kernel-2.6.2. Using libusb and hotplug.
My guess is you might have a configurationproblem.

I'm using Debian SID (kernel 2.4.22), hotplug and the package libusb is
installed. My scanner is an epson 2400, and vuescan .78 doesn't detect
my scanner (older versions was ok).
I've changed nothing to my configuration...
I hope .79 will detect my scanner !

I tested on kernel-2.4.24 too, the scanner is detected by vuescan .78.
The problem I noticed was that the 'old' scanner module was loaded by
default and that behaviour had to be disabled to give libusb
the chance to do it's job.

I've tried to unload "scanner" module, to unplug and plug the scanner,
but Vuescan doesn't detect my epson 2400...
Is there something special to configure to use "libusb" ?

It's not enough to rmmod the scanner module, it tends to get reloaded
each time you plug in the scanner. I ran modconf to disable the loading
of scanner.o (and for good measure even renamed the module in
/lib/modules/kernel<version>/kernel/drivers to sscanner.o)

Also edit the entries in /etc/hotplug as described here:
http://www.freecolormanagement.com/sane/libusb.html

In /etc/sane.d/epson.conf just put 'usb' (without quotes) that's all
you need since the rest is handled by hotplug.

In /etc/fstab I have: none /proc/bus/usb usbdevfs
devmode=0666 0 0 (the devmode is probably redundant)

Make sure you are in group 'scanner' since the epson_scanner script
sets permissions to root.scanner.

It works !!!
In /etc/hotplug/usb/libsane.usermap (Debian), I've uncommented the line
"libusbscanner" and followed the instructions to set the vendor ID and
product ID of my scanner.
I've renammed the scanner.o (can't find another way to prevent it to
load after a unplug/plug cycle) to scanner.o.sav.
In /etc/sane.d/epson.conf I've set the value to 'usb vendorID
productID'... and all are ok ! (my profile was already in scanner group)
Thanks for help, and I hope this post will help the others people who
have trouble with libusb...

Unload the scanner.o module if you have libusb on your system.

Could you let me know if this fixes this problem?

Thanks,

Yes - I just downloaded (Feb. 22.2004, 1445 Hrs EST) Extracted, and ran
- It worked. It again recognizes the scanner. Running Linux, Kernal
2.4.24, RH - as compiled by PogoLinux - another great Linux company.

Thanks Ed - sorry to be so long in replying.
