I also have 2.8p6 in both of my laptops and they are both fine.
I found that the udev rules syntax changes from time to time and had to
edit the rule to this :
cat /etc/udev/rules.d/90-ds2490.rules
SYSFS{idVendor}=="04fa", SYSFS{idProduct}=="2490", GROUP="ow", MODE="0664"
#SUBSYSTEMS=="usb", ATTRS
running:
/opt/owfs/bin/owfs -C -u -m /home/norman/1-wire --foreground
--error_level=9 2>ow.log
with ds2490 loaded or not gives the following:
norman@norman-laptop:~$ cat ow.log
CONNECT: owfs.c:main(123) fuse mount point: /home/norman/1-wire

Hi,
I am having real problems accessing my thermocron ( DS1921G ) without
being root.

If you look in the /mnt/1-wire/ directory you will see various other
directories.
I have a DS1921 ibutton which is a thermochron.
The data it holds will be in a directory beginning 21xxx
ds2490, that it
works fine on the
laptop without it blacklisted.

I have owfs running as a normal user on Ubuntu 10.04 32bit
but on Ubuntu 10.04 64 bit I can only launch it sudo.
I have myself in the fuse group on both and /etc/fuse.conf is the same on
both.
Also I am launching owfs with the same syntax on both.
On the 64bit system I get the message:
/opt/ow
Don't know if you have this working yet but I had a problem with this and it
was because owfs needs python 2.4 and Ububtu 10.04 comes with python 2.6.
I did this:-
First add the following lines to the >>start<< of /etc/apt/sources.list
deb http://gb.archive.ubuntu.com/ubuntu/ karmic main restric
I do not have one of these buttons but I do have a DS1921G which I have been
playing about with.
Have a look here

It might help solve your problem.

I have had a look at ow_1921.c in the code I downloaded for owfs-2.8p1
and altered :
{"mission/frequency", PROPERTY_LENGTH_YESNO, NON_AGGREGATE, ft_yesno,
fc_volatile, FS_r_samplerate, FS_w_samplerate, VISIBLE, NO_FILETYPE_DATA,},
to :
{"mission/frequency", PROPERTY_LENGTH_UNSIGNED, NON_AGGREG

I have a couple of DS1921G's
They only generate a new reading every minute as a minimum
and can be told to take readings every 1 to 255 minutes.
So you cannot get a shorter interval between output however often
you read the value.

I suspect it should be an unsigned int.
Although I am usually wrong and probably am this time!

Please also include python support.

Has the ability to alter the sampling frequency been added to owfs for
ds1921 ibuttons?
If not are there any prospects of getting access please?

It's Linux for me and has been since 1993.

All done again and now no complaint about ow but I get:

I think I will remove owfs, swig etc. download it all again but install swig
before owfs and see what happens.
Thank goodness for checkinstall.

Hi Gregg,
If you look you will see the swig module is enabled so I am just as puzzled
still.

Hi,
I have just started to experiment with ibuttons using owfs.
I am having trouble for a number of reasons. I have used owfs and fuse and
can read the current temperature
with a simple python script which just reads the value stored in the
1-wire/21.B5FB2200/temperature file.
I want to set
