tried your patch right away and it works! Small change, big difference ;)
I tested on platform amd64 all successful with options
-d /dev/ttyUSB0 # emulated mode
--link = /dev/ttyUSB0 # serial mode
--link = ftdi:AK0048A0 # FTDI direct communication mode
Thank you,
Martin

Hi,
just took a closer look at the patch Hans-Frieders sent earlier. The
only thing it (effectively) does, when applied to the current owfs
version, is to do more identical probes:
It sets baud/flow to something, then calls LINK_detect_serial(..). If
it fails, it does this with a few different baud/flow settings.
The thing is that the current version of LINK_detect_serial will
overwrite those baud/flow settings anyway, and probe with a bunch of
combinations.
So effectively, that patch is just calling LINK_detect_serial() 4
times instead of 1 time.
Or at least, that's what I thought first.. For the ct_serial path, it
also makes sure that gbGOOD is actually returned. In current code, the
ct_ftdi path will return gbGOOD, but ct_serial path will only
explicitly return BAD from LINK_detect_serial, not gbGOOD. For gbGOOD
it drops through and returns gbBAd...
Can (both of you, if possible) try the following patch? It will
hopefully help you.
diff --git a/module/owlib/src/c/ow_link.c b/module/owlib/src/c/ow_link.c

+ } else {

}
break;
}
If you can verify that it helps, I'll patch the code I broke when
introducing ftdi support.. and it will go in next release.. :)

Thanks for confirming.
If you want to, you can try the patch that Hans-Frieder Vogt sent to
this board. It worked for the LinkUSB.

I am trying to start owserver with a LinkUSB V 1.7 as bus master
using
the option /--link/.
I am able to start owserver with the LinkUSB V 1.7 and V 1.4 using
the
option "d" for device without any problems.
I can confirm the same behaviour here. I just upgraded my Raspberry Pi
to Raspbian stretch with owfs 3.1p5 (from squeeze with owfs 2.8). The
serial LINK is not recognised with the --link option, but OK with --
device. I didn't change anything else, juste upgraded the system.
Here are the logs :

What seams to be the problem? Anybody seen this before?
I've never seen that before. owfs and my serial LINK have both been
very reliable since at least 2003...
