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 <martinmv@penguin.cz> 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:

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: The cards that come with the umax scanners are very simple cards.
|
|
I suggest not to use this 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)
|
|
|
|
As fat as I know the PCI card is not supported by linux.

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:

|
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.
