Quick report: I have successfully implemented libftdi support in owfs
now, it works but a few things to polish up, such as retry handling etc.
A question regarding LinkUSB: have you gotten the "BREAK" functionality
to work? From the manual:

Hi everyone
Please advise if there is any possibility to speedup linkusb bus master
Compared to ds9490 it works much better in "noisy" (electric interference)
environment, but looks to be 2-3 time slower when listing 1-wire devices and
open/closing ds2406.
If that's theoretically possible i'll

I'll need to test my own device to match your findings, but two initial
thoughts:
1. You are attempting to attach to 2 devices, another owserver, and the
LinkUSB. I suspect you want owserver -p 4304 --link=/dev/ttyUSB0
2. Can you try as root to test?
3. What's your platform. The FTDI USB/serial

I don't know if this works for Linkusb since I don't have one to test.
But this does change the udev rules to tty so that ttyUSBx devices have
non-root access to a compatible serial mode. I need someone to test if
this makes the Linkusb work. Having dialout or uucp as your group id

William,
So in summary, is this a way for non-root users to use the LinkUSB?
Can you post the method or a link for all of us?

I got the udev changes to work, the weather page was right, I made a
mistake. User udev changes should start with 50 and permissions should
be 0666.

Paul,
Did you try either the udev change or the tty group? If so what
results. I'm still trying to decide between the HA7E and the Linkusb.

I tried this on Ubuntu but it didn't change my udev defaults but it is
supposed to work on opensuse.

It seems that group uucp is similar to dialout. Try change the group to
tty to get real serial i/o code which seems to not confuse the one wire
devices.

I have also blacklisted wire and ds2490, I don't know if this affects
the group id.
If linkusb it's still not working try change uucp to tty.

Ubuntu:

I tried changing the udev rules but could not find any thing
comprehensive in Ubuntu or that worked. I'm not sure it is fully
implemented in versions of 8.10 and lower. What is your group id for
ttyUSB0?

I ran the program as root (sudo).
I'm not sure what how to change permissions using udev rules.

So you didn't have to change group permission from dialout to tty? That
is leftover from my ubuntu 7.04 days. I'm still on Ubuntu 8.10 for 2
more months.

LinkUSB progress. Most of the problems are operating system ones.
In short I needed 2 changes:
1. Minor change in the code to recognize the internal version number
(LinkUSB V!.4) -- now in CVS and will be part of next release.
2. When it works, it works as both a LINK adapter (which needs the

Can you keep us updated about your progress with the linkusb. I have an
interest in using one too.

Check group setting, if it's dialout you need to change it to tty, I
include this in my owserver startup script (I am not using linkusb, but
the HL-340 usb/serial adapter);
chgrp tty /dev/ttyUSB0 ( defaults to dialout)
chmod 777 /dev/ttyUSB0 ( set this to your preferance)
From last weeks read
Has anyone had success with the LinkUSB under linux?
I just purchased one, and see this entry in dmesg:
usb 1-2.3: new full speed USB device using uhci_hcd and address 5

Hi
I have both FoxBoard and linkusb (it's based on FTDI chip). FTDI is supported
by foxboard, so
LinkUSB is recognized.
