Please, don't be inpatient and mad. I'm still learning about Ubuntu GNU/Linux.

I did try to find online solution. I tried for days, and I tried many things and How-To-s, including some from forum. But I didn't solve anything, so if there is some nice people that are able to help me, please do that.

I'm using Ubuntu 10.04 LTS, desktop, 32-bit.

I have IR-to-USB device. "Mars II, MnMII-898".

When I connect it to USB port, and use lsusb command i get this:
Code:
...
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 009: ID 066f:4210 SigmaTel, Inc. STIr4210 IrDA Bridge
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
...
I installed Ircp Tray and realized it doesn't work. :/
As I said, I tried many things. I don't know what to do next. I'm lost.

After attaching device and use of dmesg I have this:
Code:
...

In dev directory I have ttyUSB0, but nothing like irda0. Do I have to have it there at all?

When I started Ircp Tray, it told me to use:

Code:
sudo irattach /dev/ttyS1 -s
so I did, and I found out that it works only if I type:

Code:
sudo irattach /dev/ttyUSB0 -s
But Ircp Tray still don't recognize any device/phone. :/

I found this:
https://help.ubuntu.com/community/IrdaHowto
and this:
http://ubuntuforums.org/showthread.p...ight=ircp+tray

I done it with the difference I used ttyUSB0 instead of ttyS1. (Was it right?)
I realized also that there is /etc/modprobe.d/irda-utils.conf instead of /etc/modprobe.d/irda-utils file.

After I followed instructions I have this results:

Code:
user@Ubuntu:/etc$ sudo /etc/init.d/irda-utils stop
 * Skipping IrDA service: irattach (not enabled)...                      [ OK ] 
user@Ubuntu:/etc$ sudo /etc/init.d/irda-utils start
 * Skipping IrDA service: irattach (not enabled)...                      [ OK ] 
user@Ubuntu:/etc$ sudo modprobe irda0
FATAL: Error inserting nsc_ircc (/lib/modules/2.6.32-22-generic-pae/kernel/drivers/net/irda/nsc-ircc.ko): No such device
What can I do next? And what did I done wrong?

PS: Everything else I have and connect work perfect. This is last issue I have. :/
