Package: owserver

Severity: important

Dear Maintainer,
There is a regression from jessie to stretch when using owserver with
LinkUSB 1-Wire bus masters. The issue is resolved in the current
upstream source.
--Larry
* What led up to the situation?
owserver from Raspbian/jessie communicates properly with
LinkUSB 1-Wire bus masters. After a fresh install of
Raspbian/stretch on the same hardware, owserver no longer
communicates properly with the LinkUSB 1-Wire bus master.
owserver has been upgraded since jessie and the version
included in stretch is broken with respect to LinkUSB devices.
The current release of owfs from the upstream source addresses
this issue and I have confirmed that it builds and works on my
system.
From the owfs 3.2p2 changelog:
* fixed LINK-USB when not using libftdi
Summary: Raspbian GNU/Linux 8 (jessie), owfs 2.9p8-6: works properly
Raspbian GNU/Linux 9 (stretch), owfs 3.1p5-1: fails
Raspbian GNU/Linux 9 (stretch), owfs 3.2p2: works properly
* What exactly did you do (or not do) that was effective (or
ineffective)?
With a LinkUSB connected, owserver 3.1p5-1 exits immediately:
root@pi-b:~# apt list --installed ow\* libow\*

After building from upstream source (3.2p2), owserver connects and
works properly:
root@pi-b:~# /opt/owfs/bin/owserver --version
/opt/owfs/bin/owserver version:
3.2p2

^Croot@pi-b:~# echo $?

* An additional suggestion (since package work is required) is to
build with FTDI support which provides higher performance access
to FTDI devices. I used libftdi1-dev from stretch:
root@pi-b:~# apt list --installed libftdi\*
Listing... Done
