 |
|
i'm having trouble getting my scanner working in gentoo. it was working fine with slackware using libsane. first, i have to get sane-find-scanner to see it.
the result of the following two commands seems inconsistant. why does sane-find-scanner not see my scanner, yet it's listed in /proc?
| Code: |
$ sane-find-scanner
# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a SCSI driver for your SCSI adapter.
# No USB scanners found. If you expected something different, make sure that
# you have loaded a driver for your USB host controller and have installed a
# kernel scanner module.
# Scanners connected to the parallel port or other proprietary ports can't be
# detected by this program.
# You may want to run this program as root to find all devices. Once you
# found the scanner devices, be sure to adjust access permissions as
# necessary.

Have you edited /etc/sane.d/epson.conf to enable the usb option? - Also for >2.6.3 kernels you'll need to use libusb because kernel scanner support has been removed.
Do a search there's something in here about it all somewhere..... |

i think i'm having this problem because i'm using udev. the reason sane-find-scanner is failing is because there are no scanner device nodes.
i had sane working with devfs and libusb before. has anyone gotten sane to work with udev and libusb?
thanks |

Yes - it does all work with udev and libusb.
I do remember though having to make some tweaks to get it working - they are documented somewhere is these forums, but the gist of it is....
1: Create /etc/hotplug/usb/scanner
| Code: |
#!/bin/bash
if [ "${ACTION}" = "add" ] && [ -f "${DEVICE}" ]
then
chown root "${DEVICE}"
chgrp scanner "${DEVICE}"
chmod 660 "${DEVICE}"
fi
|
2: Add...
| Code: |
scanner 0x0003 0x04b8 0x010c 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0
|
to /etc/hotplug/usb.usermap, replacing 0x04b8 0x010c with the correct vendor/product id's for your scanner |

mark,
i had something similar to that already, but i replaced it with your settings (modified for my scanner model). still nothing. so what is the output of sane-find-scanner on your computer?
thanks |

Also...
What have you got in your USE flags?
If you haven't got usb in there, you'll need to add it and re-emerge sane-backends |
