Hi!
I'm trying to run Canon MP250 scanner.
It worked with sane-backend 1.0.23, and is broken since 1.0.24.
I took sane from git. Below I attached a part of sane log. I added
several "here we are" lines to see source file name and line of code.
Problems started after "sane_control_option(handle=0x8080c00,option=17"
option=17 is opt_button_1.
In 1.0.24 these lines were added to pixma.c control_option() function:
+ case opt_button_1:
+ case opt_button_2:
+ case opt_original:
+ case opt_target:
+ case opt_scan_resolution:
+ /* poll scanner if option is not cached */
+ if (! ss->button_option_is_cached[ BUTTON_GROUP_INDEX(n) ] )
+ update_button_state (ss, info);
+ /* mark this option as read */
+ ss->button_option_is_cached[ BUTTON_GROUP_INDEX(n) ] = 0;
control_option() form pixma.c call update_button_state(),
then pixma_wait_event(),
mp150_wait_event(),
handle_interrupt() from pixma_mp150.c,
send_time().
Send a few bytes over USB and wait for device respond.
Device never responds.
If I comment out all these lines marked with '+' in pixma.c
control_option() function my MP250 works.
On the other hand with this patch to sane git and without any other changes:
diff --git a/backend/pixma_mp150.c b/backend/pixma_mp150.c
index 4f8b232..7ab9e0f 100644

{
/* More than one event can be reported at the same time. */
- if (buf[3] & 1)
- send_time (s);
+ if (s->cfg->pid != MP250_PID)
+ {
+ if (buf[3] & 1)
+ send_time (s);
+ }
if (buf[9] & 2)
query_status (s);
if (buf[0] & 2)
my MP250 works too.
In pixma_mp810.c there is a comment:
/* FIXME: some scanners hang here */
near send_time() call. Perhaps, MP250 doesn't need send_time()?
