Problem with usbfs and scanner

Hi,

I'm desperately trying to make my scanner work...

- Epson Perfection 1250 Photo USB
- libusb, sane compiled with -USE=usb

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

sane-find-scanner says:
found USB scanner (vendor=0x04b8 [EPSON], product=0x010f [EPSON Scanner 010F], chip=LM9832/3) at libusb:003:003

When I try to use kooka or iscan dmesg says:
usb 3-2: usbfs: USBDEVFS_BULK failed ep 0x82 len 1 ret -110
usb 3-2: bulk timeout on ep2in
usb 3-2: usbfs: USBDEVFS_BULK failed ep 0x82 len 4 ret -110
usb 3-2: usbfs: interface 0 claimed while 'kooka' sets config #1

I've tried kernel 2.6.7 and 2.6.8-rc2, it makes no difference.

Any ideas?

Thx
Bowmore

Bowmore,

Have you got long timeouts configured in your kernel?
Whats in your hot plug script

Hi NeddySeagoon,

I haven't configured any timeouts in the kernel, so there should be the defaults.

Here's my script /etc/hotplug/usb/libusbscanner

#!/bin/sh

# This file is part of sane-backends.
#
# This script changes the permissions and ownership of a USB device under
# /proc/bus/usb to grant access to this device to users in the scanner group.
#
# Ownership is set to root:scanner, permissions are set to 0660.
#
# Arguments :
# -----------
# ACTION=[add|remove]
# DEVICE=/proc/bus/usb/BBB/DDD
# TYPE=usb

if [ -z "$DEVICE" ] ; then
IF=$(echo $DEVPATH | sed 's:$bus/usb/devices/$$.*$-$.*$:\2:')
DEV=$(echo $DEVPATH | sed 's:$bus/usb/devices/$$.*$-$.*$:\3:')
DEV=$(expr $DEV + 1)
DEVICE=$(printf '/proc/bus/usb/%.03d/%.03d' $IF $DEV)
fi

if [ "$ACTION" = "add" -a "$TYPE" = "usb" ]; then
chown root:scanner "$DEVICE"
chmod 0770 "$DEVICE"
fi

# That's an insecure but simple alternative
# Everyone has access to the scanner

# if [ "$ACTION" = "add" -a "$TYPE" = "usb" ]; then
# chmod 0666 "$DEVICE"
# fi

While the scanner is connected ls -l /proc/bus/usb/003/ says:
-rwxrwx--- 1 root scanner 57 Jul 24 22:32 002

Thx
Bowmore

Bowmore,

That all looks good and the long timeout option has been removed from 2.6.7. I don't know when it went.

Which backend are you using?
http://www.freecolormanagement.com/sane/ says the Plustek backend works with the Perfection 1250. i.e. not the Epson one.

Hi NeddySeagoon,

I use the plustek backend.
I've forgotten to say that the scanner has worked with kernel 2.4.x

But if I'd go back, my dvd-writer wouldn't work...

Thx

Bowmore,

I'm out of ideas just now.

Hello Bowmore,

had you resolved your problems? I have exactly the same problem now. Could you give me a clue?

Thanks
