I just got myself a Epson636u Scanner and am having a bit of a problem with it.
I am new to scanning in general, so as I will try to give all the info that one
might need to help me on this, feel free to hit me with the clue stick if I
leave something out.
This is on a FreeBSD 4.4RC machine. Scanner is a Epson 636U, USB.
On FreeBSD, my scanner is connecting to the sytem as:
uscanner1: EPSON Perfection636, rev 1.00/1.04, addr 3
I have made sure to have my epson.conf file to read:
usb /dev/uscanner1
And I have tried to make sure that permissions on my permissions on the device
correct:
crw-rw-rw- 1 root operator 156, 1 Sep 9 00:57 uscanner1
Now, onto the problem...
Half the time, when I run xsane it hangs. Doing a trus on xsane, I can see that
every time it hangs at this point:
open("./epson.conf",0,0666) ERR#2 'No such file or
directory'
open("/usr/local/etc/sane.d/epson.conf",0,0666) = 6 (0x6)
fstat(6,0xbfbfec8c) = 0 (0x0)
read(0x6,0x80fd000,0x2000) = 399 (0x18f)
open("/dev/uscanner1",2050,027757766774) = 7 (0x7)
write(7,0xbfbfd476,2) = 2 (0x2)
If I ctrl-c the process and re-run it enough, it will find the scanner. Once it
does, and I try to do a preview, it will hang as well:
ioctl(3,FIONREAD,0xbfbfdfd8) = 0 (0x0)
poll(0x840f210,0x2,0x0) = 0 (0x0)
open("/dev/uscanner1",2050,027757763660) = 6 (0x6)
write(6,0xbfbfe8a6,2) = 2 (0x2)
At this point, if I turn off and on the scanner, it will pop up with a error
message, and then be able to do a preview. About 50% of the time when doing
this preview, the process will core dump.
writev(0x3,0xbfbfc434,0x1) = 8192 (0x2000)
writev(0x3,0xbfbfc434,0x1) = 280 (0x118)
SIGNAL 11
SIGNAL 11
Process stopped because of: 16
process exit, rval = 139
Segmentation fault (core dumped)
The other half of the time, the preview will come through. Upon trying to do
any other funtion that would involve talking to the scanner, the process will
then core dump.
Has anyone seen anything like this before? I have a saved core file if that
might help anyone.
Advice on where to go from here?
Thanks!
Jim
