I'm using 1.0.17.
is this distincion made here:
<code>
snapscan-options.c-278- case PERFECTION2480:
snapscan-options.c-279- if (ps->hconfig_epson & 0x20)
snapscan-options.c-280- {
</code>

The problem I've now discovered is that sth. goes wrong ;)
Couple of months ago I used this scanner under Slackware, with epkowa backend.
Worked like a charm.
Now I've got ubuntu "breezy" (why?, why?, why?), and I have rebuilt backends
1.0.17 by myself (took it from 'dapper', originally 'breezy' has 1.0.15).
I've decided to use snapscan, hence I don't have epkowa at all.
Two days ago I did some debug logs for Paul (he's working on OS/2), but I used
the 'scanimage' command, sth. like:
<code>
scanimage -d snapscan:libusb:004:008
</code>
But now, I wanted to send You a log from xsane, and to my surprise xsane says
"no device found" :(
I've checked, and after plugging the scanner to USB, in /var/log/messages
I've got only:
<code>
Feb 18 13:29:34 localhost kernel: [4523557.302000] usb 4-3: new high speed USB
device using ehci_hcd and address 18
</code>
No device nodes are created for the scanner.
I quickly checked udev-rules, and they seems to be OK (well, I'm not an expert
in it).
But to be sure I've added a file:
/etc/udev/rules.d/10-local.rules
with following content:
<code>
BUS="usb" SYSFS{idProduct}=="0121" SYSFS{idVendor}=="04b8" NAME="scanner"
SYMLINK="usb/epson_scanner"
</code>
After restarting udev both entries are created (/dev/scanner
and /dev/usb/epson_scanner) but xcane still complains that "no device found".
Also if I try:
<code>
scanimage -d snapscan:/dev/scanner
</code>
result is the same.
So it seems that before I go any further, I've got to make my scanner work at
all on this crazy distro :)
If You've got any suggestions, I'll apreciate that.
regards,

yes.

If scanimage works xsane should work as well. If it doesn't there's
probably something wrong with your backend installation, e.g. you may
have two versions of sane-backends installed (one in /usr/lib/sane.d,
another in /usr/local/lib/sane.d)

You don't need the device nodes. The backend should always use libusb,
which doesn't need the device nodes. You can check what's going on by
running
SANE_DEBUG_SNAPSCAN=255 xsane
If you don't get any output try
SANE_DEBUG_DLL=255 xsane
and check that the snapscan backend is loaded at all. If it isn't,
check the dll.conf configuration file.
