------------------------------------------------------------------------------- Q: compiling sane aborts with error "virtual memory exhausted" on slackware linux with gcc. What goes wrong? A: The optimization set by "-O2" makes problems, try which one of the following calls work: make CFLAGS="-g -Wall -O1" make CFLAGS="-g -Wall -O" make CFLAGS="-g -Wall" ------------------------------------------------------------------------------- Q: Will there be a support for the UMAX-parallel-port-scanners? Q: Will there be a support for the UMAX-USB-scanners? A: UMAX published their SCSI-protocol for scanners. However they have not so far published parallel port and USB protocols. Without the protocol documentation I will not work on a driver. Martin Mevald has worked on a parallel-port-driver but stopped the development. The Astra 2200W does work when connected via SCSI. It could work with SCSI-via-USB-driver and connected via USB, but that is not tested. ------------------------------------------------------------------------------- Q: I get a black area at the top of the image. What's wrong? A: This is a problem of some scsi-drivers. Update the driver for your scsi-adapter or update the operating system/kernel. For advansys-scsi-cards update to a new kernel which includes at least the driver version 3.1E of the advansys-scsi-driver. Take a look at: http://www.advansys.com/linux.htm ------------------------------------------------------------------------------- Q: I want to use the scsi-card that comes with my umax scanner. What card is it and is it supported by my os? A: There are at least two kind of scsi controller cards that come with UMAX scanners. ISA-Card: The ISA-cards that come with the umax scanners are very simple cards. I suggest not to use these cards. If you really want to try: the UDS-IS11 ISA-card is a DTC3181E-card based on the NCR5380-chip. On linux you may have the chance to get it work with the recent g_NCR5380-driver. The card does not have IRQ/DMA. Try the following option for kernel: dtc_3181e=0x280,255 or use the following command: insmod g_NCR5380 ncr_irq=255 ncr_addr=0x280 dtc_3181e=1 - ncr_irq=255 : no IRQ, no DMA - ncr_irq=254 : autoprobe IRQ - ncr_addr : can be: 0x220 0x240 0x280 0x2A0 0x2C0 0x300 0x320 0x340 (Thanks to Colin Brough and Hans Schaefer for that tip) PCI-Card: Some UMAX Scanners come with a PCI SCSI controller card DOMEX DMX3191E. This card shall be compatible to the Advansys ABP940U (Chip: Advansys ASC3030). The card shall work without problems with the Advansys SCSI driver for linux. (Thanks to Volker Ossenkopf for that tip) ------------------------------------------------------------------------------- Q: I use linux with a NCR/Symbios logic SCSI-Controller, sane does not work right. A: There are two differen drivers in the linux Kernel/modules. Use the BSD-driver ncr53c8xx or sym53c8xx. ------------------------------------------------------------------------------- Q: Does SANE and the umax backend work on LinuxPPC / big endian machine ? A: There are people using the sane-umax on a LinuxPPC (big endian) machine. Other people write that they can not scan on a LinuxPPC. It looks like this is a problem with the driver of the scsi card. The "MESH" SCSI card is reported to work. The NCR53C94 SCSI card seems not to work. ------------------------------------------------------------------------------- Q: I am using an AM53C974 based scsi card with a umax scanner, the system freezes when I start a scan, what can I do? A: Try the recent driver for the scsi card, take a look at: http://www.garloff.de/kurt/linux/dc390/index.html ------------------------------------------------------------------------------- Q: Sane hangs or crashes when I start a frontend for sane, what can I do? A: Sometimes the backends that are not used make problems. Edit /usr/(local)/etc/sane.d/dll.conf and comment out everything but the backend you need. ------------------------------------------------------------------------------- You find a lot of tips and informations in the internet.
