Thank you for such quick response, allan. Do you mean to say that the value
of maxlen is determined by the frontend? On xsane application, maxlen value
is 8192 when using acquire preview and then value of maxlen is 65536 when
using scan function. Our external backend currently reads images by row o

Thanks for the log. It looks very much like something is wrong with
the registration of the interpreter. W
Because different frontends have different requirements. Some try to
save memory, some try to maximize speed by using large buffers, some
try to fill a network packet exactly. You can (and should expect) to
get any value of maxlen from 1 byte to perhaps a 1M, maybe more.

why does the value of maxlen vary from various frontends?

When I tested the scanner on WIN7 I found that the USB-cable
seemed to be loose. I fixed the cable. The scanner worked now.
Then I returned to LINUX.
epkowa.c:
=
name = rewrite_name vendor(Epson) name(epkowa:usb:002:004)
returns name(Epson (unknown model) [epkowa:usb:002:004])

Slackware is not officially supported and I don't think there has been
any testing on 4.x kernels. The list of "supported" distributions has
aged a lot (all distributions seem from 5 or 6 years ago).

hi,
how is the argument maxlen determined in sane_read() function?
SANE_Status sane_read (SANE_Handle h, SANE_Byte * buf, SANE_Int maxlen,
SANE_Int * len);
Thanks for your help.
