Hi all, I just recently was given an HP scanjet 4c and I'm trying to get it working with my system. So far no luck. I guess most obivious is that it was known to be working on Win98 before I got it .. so I'm running Linux 2.4.19 on a PPC machine. Compiled SANE-1.0.9 from source using gcc-3.2.1 . . compilation was fine, uneventful. SCSI generic is compiled into the kernel and the scanner is recognized at boot time as /dev/sgc. I have an internal scsi cd-rw drive that is working fine with cdrecord (uses scsi-generic) and an old external syquest which are both working fine also so SCSI looks ok. Here's my output from cat /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: YAMAHA Model: CRW4416S Rev: 1.0h Type: CD-ROM ANSI SCSI revision: 02 Host: scsi0 Channel: 00 Id: 01 Lun: 00 Vendor: SyQuest Model: EZ135S Rev: 1_12 Type: Direct-Access ANSI SCSI revision: 02 Host: scsi0 Channel: 00 Id: 02 Lun: 00 Vendor: HP Model: C2520A Rev: 3503 Type: Processor ANSI SCSI revision: 02 I've created a symlink from /dev/scanner to /dev/sgc and when I run sane-find-scanner, it sees an HP C2520A at /dev/sgc, /dev/sg2 and /dev/scanner. So far so good. When I run scanimage -L however, no scanners are found. Note: for testing right now, I'm running as root and I checked the permissions of /dev/sgc just to be sure (0660) I searched the mail archives and couldn't find any recent issues with PPC and the HP backend so I went to the faq. Found the HP faq and looked at that. Mentioned device i/o errors with certain scsi cards and mentioned upgrading the HP backend to v1.0.1 So, first I ran SANE_DEBUG_HP=3D255 scanimage -L with the old backend (v0.96 IIRC) and captured the output then I upgraded to v1.0.1.=20 Recompiled just find but That one dumped core on me with an error scanimage: hp-option.c:3501: sanei_hp_optset_scanmode: Assertion `mode' failed. when I ran scanimage -L. =20 I ran SANE_DEBUG_HP=3D255 scanimage -L with that backend and captured that output as well. With each backend, it appears that sane and my HP4C are talking but that SANE is getting unexpected responeses (endian problems?) So, I'm not sure where to go with this. I don't know myself what the communication "should" look like. I'd be happy to post my debug output though it's rather lengthy. I figured it'd be better to send it off list to anyone who could make sense of it. Thanks for any help anyone can give Cheers, Keith --=20 <><><><><><><><><><><><> Keith Clayton ke...@claytons.org "If you don't trust me with your source code, why should I trust you with my computer?"
