I've been working on getting usb scanners to work with a couple of
slackware 10 systems running 2.6.7. The main problem is that there does
not seem to be any device created for the scanner (ex. /dev/scanner).


dmesg when connecting the scanner:
usb 3-2: new full speed USB device using address 3

sane-find-scanner detects it properly:
found USB scanner (vendor=0x03f0, product=0x0601 [HP ScanJet 6300C]) at
libusb:003:003

The scanner vendor/product id values are found in
/etc/hotplug/usb/libsane.usermap


There does not appear to be any usb scanner device file.

The command
find /dev -name "*scan*"
does not find anything.

/etc/sane.d/hp.conf does contain the appropriate entry for the scanner.

Looking at /etc/udev/permissions.d/udev.permissions it looks like
/dev/scanner and /dev/usb/scanner? files should be created but are not
there for some reason when the scanner is connected.

What am I missing?

Why do I always find the answer immediately after posting a message to a
list/group?? Running "xsane hp:libusb:003:003" works perfectly. I guess
I was looking for a device that I didn't need.

Just keep posting then - just make yure you don't forget to report your
findings, so folks on groups.google.com will have an easy time, too

I've been having trouble as well, i thought it was a udev problem,
but after your post it appears to not be the case.
Where did you get "hp" from, is that hp's sane backend? I have an epson
scanner and i tried xsane epson:libusb:004:005 (my scanner entry) and i
get failed to open device, invalid argument. I've also tried ep instead of
epson. Sane's backend for epson scanners is epson, so i was hoping you
could give me a few pointers, or maybe the link to where you got that
info. Been searching for 3 days now

thanks

I have an HP scanner, and I'm afraid I can't be much help, because it seems
that somehow it gets "noticed" automagically:

Try plustek:libusb:004:005

Obviously if the scanner gets switched off then on again the last number
will change (use sane-find-scanner again).

If you want to play, Epson's Iscan is quite good.

ok I want mine to work also
worked fine with 8.1, 9.0, 9.1 and 10.0 with the 2.4x

things appear to be a bit different with 2.6x


dmesg:
usb 1-1: new full speed USB device using address 2

scanner is listed in /etc/hotplug/usb/libsane.usermap

Acer Peripherals Inc.|Prisa AcerScan 620U & 640U
libusbscanner 0x0003 0x04a5 0x2060 0x0000
0x0000
0x00 0x00 0x00 0x00 0x00
0x00 0x00000000

But (evan as root):
scanimage -L
No scanners were identified.

sane-find-scanner
No USB scanners found

seems I may need a line like following:
(I quote from this thread):
Running "xsane hp:libusb:003:003" works perfectly. I guess

how do I create one for my scanner?


when I was running 8.1:
sane-find-scanner: found USB scanner (vendor = 0x04a5, product =
0x2060) at dev
snapscan.conf has # Benq/Acer/Vuego 640U
usb 0x04a5 0x2060

kernel 2.6 uses libusb. Also make sure you are mounting usbdevfs. In fstab
i have
none /proc/bus/usb usbdevfs devmode=666,auto 0 0
In /etc/sane.d make sure only your backend is executable.
(chmod +x acer.conf) The acer.conf is only a guess. Make sure that's the
proper backend file for your scanner. Once you determine your proper
backend, open the file and for the device just use "usb" *no quotes and on
it's own line. THat tells sane that you are using libusb.

Hope that does the trick for you.

thanks for the quick reply/tip though I don't think I understand any
of it.

thanks for the hints
added the line to fstab - now scanner works for root.
and I get some acitivity from sane-find-scanner and scanimage -L

I referenced my "backend" in snapscan.conf
(/usr/local/bin/u222v067.bin )
and added usb to snapscan.conf
making snapscan executable didn't seem to effect anything

now to get it to work as a user.
