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
Hi all,
Having problems setting up - I'd be grateful for a pointer or two in the
correct direction...

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

Thanks for the reply.

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 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

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.

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

I just purchased one, and see this entry in dmesg:

In short I needed 2 changes:

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)

As I recall, the FoxBoard is an embedded computer (Axis etrax cpu)

linux. It looks like several build systems are available, many based
on fairly modern kernels. uClibc, openmwrt, are all supported by owfs,

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