Hi all,
I came into possesion of a umax Astra 1200S, and would like to get it going
on my FreeBSD machine. Here is the problem :
# scanimage-list-devices
device 'umax:/dev/scanner' is a UMAX Astra 1200S flatbed scanner
device 'pnm:0' is a Noname PNM file reader virtual device
device 'pnm:1' is a Noname PNM file reader virtual device
After upping SANE_DEBUG_UMAX, I get the following output, where irrelevant
parts are snipped for brevity :
# scanimage -d umax > output.ppm
....
[umax] fast preview function = 0
[umax] trying to reposition scanner ...
[umax] wait_scanner
that's were scanimage hangs and the following messages appear
[umax] scanner reports Device busy, waiting ...
Aug 1 17:02:15 dorothy /kernel: uk1(aha0:4:1): timed out
if the scanner now get's power-cycled, it continues on until :
...
[umax] scanner ready
[umax] reader_process: buffer of 17850 bytes read; 0 bytes to go
[umax] reader_process: finished reading data
...
[umax] sane_read: read 0 bytes
[umax] do_cancel
[umax] killing reader_process
[umax] reader_process killed
[umax] trying to reposition scanner ...
[umax] wait_scanner
[umax] scanner ready
[umax] scanner repositioned
[umax] trying to release scanner ...
[umax] wait_scanner
Here it stops again (same messages as above) and another power cycle is in
order, then it goes :
[umax] scanner ready
[umax] scanner released
[umax] closing scannerdevice filedescriptor
[umax] close_pipe
[umax] sane_cancel
[umax] sane_close
[umax] sane_exit
which then completes the scan.
Here is the machine info : Pentium 133 / 32 Meg FreeBSD 2.2.8 release SCSI
host adaptor is a adaptec 1542 CP which get's detected as follows :
> aha0 at 0x330-0x333 irq 12 drq 5 on isa
I've changed the BIOS settings as per suggestion in the mailing list
archives and disabled disconnect/reconnect.
the Scanner is a umax astra 1200 S-C, Firmware Rev. 3.1, detectet as follows
:
> (aha0:4:0): "UMAX Astra 1200S V3.1" type 6 fixed
SCSI 2
> uk0(aha0:4:0): Unknown
> (aha0:4:1): "UMAX Astra 1200S V3.1" type 6 fixed
SCSI 2
> uk1(aha0:4:1): Unknown
I'm running SANE-1.0.1
/dev/scanner is symlinked to /dev/uk1
I've read the recent thread with Lee Nevo, where it turned out to be a SCSI
termination problem, so I went off buying new (shorter) cables and
rearranged the external SCSI bus to be terminated by a device with active
termination (External CD-ROM) -- the problem is to get a 25DB active
terminator, so I opted for this solution-same problem persists. The total
cable lenght now is ~ 120 cm, there are no devices on the internal side of
the host adaptor and the host adaptor is set to terminate.
The reason why I don't think that this is a termination problem is that
those problem should show a bit more "randomness". I've run it ~ 50 times
now, changing configurations etc. and it ALWAYS shows the exact same
behavior (unless I leave the termination off altogether, then it doesn't
even start talking to the scanner).
In addition, it hangs on the first "[umax] trying to reposition scanner
...", but it succesfully completes the second one after it's done
scanning...
There was also a mentioning of the astra 1200S with Firmware Rev. 2.9 and
ext. Power-supply "could make problems" on Olivers Site
http://www.wolfsburg.de/~rauch/sane/sane-umax-scanners-doc.html
<http://www.wolfsburg.de/~rauch/sane/sane-umax-scanners-doc.html>; Anyone
know if that's still the case with Rev. 3.1 and does anyone know what the
exact symptoms of the problems are ??
Thanks in advance if anyone could shed a light on this. If more information
is needed I'm happy to provide what's necessary.
Thanks
