Hello,
I was expecting something like that.
All DBG_io2 a mere traces, and I don't see how much they slow down
things. Since I don't have this kind of problem on my hardware, I need
your help. I don't see no other approach than trial and error.
1 - compile sources
2 - set logs to 7
3 - check that scanner is working with compiled sources and the log
level
4 - change a line where there is DBG_io2 level in DBG_data so it
isn't traced any more, write down the line number
5 - compile and run, if it is still working, go to step 4 and
change one more debug trace
6 - since it isn't working anymore, you have find where a pause
must be set, please send it to me
Hi Stef,
Your more precise instructions including the "runit" script got me
through step 3. I confirmed that it's broken with logs at 6 and works
with logs at 7. Now I'm stuck at step 4. What file contains the lines
to be changed? I grepped and found several files that contain these
strings. I guess I need more precise instructions, but I'm confident I
can follow them.

Hello,
the file to modify is backend/genesys_low.c
For instance, line 251 turn :
DBG( DBG_io2, "sanei_genesys_read_hregister(0x%02x)=0x%02x\n",reg,*val);
into:
DBG( DBG_data, "sanei_genesys_read_hregister(0x%02x)=0x%02x\n",reg,*val);
Regards,
Stef
Hi,
I had the logic of the test backward when I tested. I re-read and
re-tested. I found that changing the DBG_io2 on line 964 to DBG_data is
what breaks things. I tried the other occurrences of DBG_io2 and
changing them does not break things. (lines 251 402 *964 1345 1649)
Please let me know where and how to set a pause and I'll test it.
John
