[lm-sensors] Help to make lm-sensors work with an Asus TUSL2-C

[Mauro Molinari <mauromol@tiscali.it>]

Hello to all,
I'm new to lm-sensors.

I'm writing because I need help to configure lm-sensors to work on an 
old Asus TUSL2-C motherboard. I read a lot of documentation on 
lm-sensors website and wiki and I did some searches with Google, however 
I can't understand what I'm doing wrong.

First of all, I'm using a Linux distribution based on Debian Squeeze: 
precisely, it's OpenMediaVault 0.4. "uname -a" shows:
Linux openmediavault 2.6.32-5-686 #1 SMP Sun Sep 23 09:49:36 UTC 2012 
i686 GNU/Linux
and "sensors -v" shows:
sensors version 3.1.2 with libsensors version 3.1.2

I installed lm-sensors with "apt-get install lm-sensors". Then, I 
launched "sensors-detect". The problem is: no sensor is found. The only 
relevant output is given at the end:

---
Do you want to probe the I2C/SMBus adapters now? (YES/no):
Using driver `i2c-i801' for device 0000:00:1f.3: Intel 82801BA ICH2

Sorry, no sensors were detected.
---

So, if I understand it correctly, the i2c-i801 driver is found and 
queried, but no sensors are found there.
I then made some researches on the Internet and found the following 
information.

At:
http://lists.lm-sensors.org/pipermail/lm-sensors/2005-March/011402.html
a user says that lm-sensors works with Asus TUSL2-C. I also found out 
the example configuration file at:
http://www.lm-sensors.org/browser/lm-sensors/trunk/etc/sensors.conf.eg?rev)64
which mentions the TUSL2-C: for it the AS99127F chip should apply.
Then, if I look at:
http://www.lm-sensors.org/wiki/Devices
I actually find that the AS99127F chip is supported by the w83781d 
driver since kernel 2.5.67, however the sensors-detect program shows this:
Probing for `Winbond W83781D' at 0x290...                   No

Further searching brings this:
http://www.lm-sensors.org/ticket/1317
which seems to say that it's a known issue that no sensors are found on 
the TUSL2-C. It also says to see the FAQ, but the FAQ doesn't say 
anything in particular for this motherboard or for that chip.

I then tried the following:
- run "modprobe w83781d", then run "sensors": still "No sensors found"
- created a file named "asus.conf" under /etc/sensors.d (it's not clear 
to me if the custom configuration file in /etc/sensors.d can be named as 
I like, or if I must give it a specific name...) and put in it all the 
contents from sensors.conf.eg related to the AS99127F chip, then run 
"sensors" or even "sensors -c /etc/sensors.d/asus.conf" (do I need to 
specify the config location??): still "No sensors found"

I don't know what else to try! :-(

Thanks in advance,
Mauro.
