[sane-devel] SANE 1.0.18 and the NSLU2 running OpenWRT
I am having terrible problems getting SANE to work with my AVISION scanner on the NSLU2. I did compile SANE 1.0.18 for the NSLU2, but don't think it is the code. Anyone have any suggestions? I have the following modules loaded: root at OpenWrt:/dev# lsmod Module Size Used byNot tainted usb_storage57035 0 sd_mod 10384 0 scsi_mod 55784 2 usb_storage,sd_mod usbserial 20336 0 cdc_acm 8068 0 ehci_hcd 25004 0 uhci_hcd 18700 0 ohci_hcd 13348 0 usbcore79548 7 usb_storage,usbserial,cdc_acm,ehci_hcd,uhci_hcd,ohci_hcd Here are my installed applications: root at OpenWrt:/dev# ipkg list base-files-ixp4xx-2.6 - 9-7899 - bridge - 1.0.6-1 - busybox - 1.4.2-2 - dnsmasq - 2.38-1 - dropbear - 0.49-2 - hotplug2 - 0.9+r102-1 - iptables - 1.3.7-1 - kernel - 2.6.21.5-ixp4xx-1 - kmod-scsi-core - 2.6.21.5-ixp4xx-1 - kmod-usb-acm - 2.6.21.5-ixp4xx-1 - kmod-usb-core - 2.6.21.5-ixp4xx-1 - kmod-usb-ohci - 2.6.21.5-ixp4xx-1 - kmod-usb-serial - 2.6.21.5-ixp4xx-1 - kmod-usb-storage - 2.6.21.5-ixp4xx-1 - kmod-usb-uhci - 2.6.21.5-ixp4xx-1 - kmod-usb2 - 2.6.21.5-ixp4xx-1 - libgcc - 4.1.2-9 - libjpeg - 6b-1 - libpthread - 0.9.28-9 - libusb - 0.1.12-1 - mtd - 5 - ppp - 2.4.3-7 - ppp-mod-pppoe - 2.4.3-7 - sane-backends - 1.0.18-1-TDS - sane-libs - 1.0.18-1-TDS - uclibc - 0.9.28-9 - udev - 106-1 - udevtrigger - 106-1 - usbutils - 0.72-1 - xinetd - 2.3.13-2 - I am using the 07-09 kernel (I have also tried todays and the 7.06 release): root at OpenWrt:/dev# uname -r 2.6.21.5 Here is what is happening with SANE: root at OpenWrt:/dev# SANE_DEBUG_AVISION=255 SANE_DEBUG_DLL=255 SANE_DEBUG_SANEI_USB=255 scanimage -d avision --resolution=50 > /tmp/tmp.pmg [sanei_debug] Setting debug level of dll to 255.

note that i have never really used any avision equipment, but you might try disabling the gamma table in the conf file. man sane-avision for more. allan On 7/12/07, David Solomon wrote: > I am having terrible problems getting SANE to work with my AVISION > scanner on the NSLU2.

Hi, that's a common problem of many backends, please file a bug at our alioth bug tracker. See bug #303681 http://alioth.debian.org/tracker/index.php?func=detail&aid=303681&group_id=30186&atid=410366 for a similar bug. regards -- jochen

Allan, I tried disabling Gamma in the code (couldn't get it work in the config for some reason). Now it is having a problem at the sense. Could this be related to usb issues? Is udev required when using libusb?

my apologies- Jochen appears to have been correct. though the data payloads are correct (which is what i initially inspected), the commands before them are built from un-aligned structs, and extended from 10 to 12 bytes in both cases, IIRC. i guess you could try adding the gcc specific alignment pragmas, though that is beyond me. i know such a patch was floating around for plustek backend. sorry for the confusion. allan On 7/16/07, David Solomon wrote: > Allan, > > I tried disabling Gamma in the code (couldn't get it work in the > config for some reason).

Thank you. I have filed the bug. Also, I am trying to use some #pragma pack statements to see if they will work.

I think you are right. I am trying some pragma pack statments to see if they will help. I looked at some of the plustek_usb header changes and found that they used: "#define PACKED8 __attribute__ ((packed,aligned(1)))" and "#define PACKED16 __attribute__ ((packed,aligned(2)))" statements to pack the structures. I may have to use these myself, but I am unsure where to add (possible in the sanei_usb_write_bulk?). Thank you for the help. I am going to get up-to-my-elbows in code now. ;-) (Sorry for the double emails, but I keep forgetting to hit reply-all.

Allan, Do I add them to all of the command structs or just the Avision_Connection? David Solomon On 7/16/07, m. allan noah wrote: > On 7/16/07, David Solomon wrote: > > I think you are right.

OK. I have it scanning, but it looks as though it is failing to close the scanner. Sane completes, but the scanner never ejects the paper and just freezes.
