Hi, I am using Redhat AS 3, update 7. kernel string 2.4.21-40.EL.
I am developing sane backend for USB hand held image scanner. Problem :- When I connect the USB device and run 'sane-find-scanner' command, it does not detect my usb scanner. It displays error message as, 'make sure usb host controller driver is installed and kernel scanner module is loaded'. 1) The files present in /dev/usb are :- scanner0 scanner10 scanner12 scanner14 scanner2 scanner4 scanner6 scanner8 scanner1 scanner11 scanner13 scanner15 scanner3 scanner5 scanner7 scanner9 2) the files present in /etc/hotplug are :- blacklist ieee1394.agent pci pci.rc usb.agent usb.handmap usb.usermap hotplug.functions net.agent pci.agent usb usb.distmap usb.rc 3) output of lsmod is:- Module Size Used by Not tainted ide-cd 33920 0 (autoclean) cdrom 32416 0 (autoclean) [ide-cd] i810_audio 29784 0 (autoclean) ac97_codec 17736 0 (autoclean) [i810_audio] soundcore 6436 2 (autoclean) [i810_audio] agpgart 57752 6 (autoclean) audit 89944 2 (autoclean) usbserial 23420 0 (autoclean) (unused) parport_pc 18756 1 (autoclean) lp 8964 0 (autoclean) parport 36832 1 (autoclean) [parport_pc lp] autofs4 16152 0 (autoclean) (unused) e100 28264 1 mii 4516 0 [e100] floppy 56624 0 (autoclean) sg 36236 0 (autoclean) (unused) scsi_mod 107180 1 (autoclean) [sg] microcode 5688 0 (autoclean) keybdev 2944 0 (unused) mousedev 5524 1 hid 22244 0 (unused) input 5888 0 [keybdev mousedev hid] ehci-hcd 20008 0 (unused) usb-uhci 25740 0 (unused) usbcore 77408 1 [usbserial hid ehci-hcd usb-uhci] ext3 85864 2 jbd 50956 2 [ext3] ===========================================================================\ can anyone guide me what is wrong? Where to look for usb scanner device file? is it necessary to install, usb-serial port emulator driver(kernel module) for scanner device on linux? (as usbserial module is already present) Thanks in advance, Rupesh Tarpara http://www.patni.com World-Wide Partnerships.

I have seen it on our OpenSuSE mirror here at Mandrive. What I have done now is suggesting to the upstream developers to make two packages, one with the frontend and one with the backend, to be more distro-friendly. I have no answer yet, lets see what they say. Till
