Laptop CIR Transceiver & Lirc Problem

[sokairyk]

Hello!

I have a Hauppage TV Tuner and I want to use its remote with my Acer 5920G Laptop, which has a built-in IR device.

The remote works fine with lirc on my desktop PC.

My Laptop runs Ubuntu Gutsy x64 with the 2.6.22-16-generic kernel.
I use the same lircd.conf file with my desktop PC as I'm using the same remote.

I installed lirc and selected SIR (Built-in IrDA) and played around a little with my serial ports and /etc/lirc/hardware.conf but I didn't get any results when running irw...

When I run "sudo cat /proc/tty/driver/serial" I get:

serinfo:1.0 driver revision:
0: uart:unknown port:000003F8 irq:4
1: uart:unknown port:000002F8 irq:3
2: uart:unknown port:000003E8 irq:4
3: uart:unknown port:000002E8 irq:3

whether the lirc_sir module is loaded or not.

I have turned the LOAD_MODULES to "false" on hardware.conf so I can load the lirc_sir module with io, irq parameters (e.g. sudo modprobe lirc_sir io=0x03F8 irq=4) but none of the above serial ports gave any results with either "sudo irw" or "sudo mode2 -d /dev/lirc0"

I booted from my Vista partition and I got the CIR Transceiver driver resources which are:

I/O 0600-0607
I/O 0620-063F
IRQ 4

I tried:

"sudo modprobe lirc_sir io=0x0600 irq=4"
"sudo modprobe lirc_sir io=0x0620 irq=4"

but neither worked.

The on-board CIR chipset is a Winbond WPC876xL

On every try my actions are:
-stop lirc daemon
-unload lirc_sir module
-load lirc_sir module with new parameters
-start lirc
-test with irw/mode2

Below is my hardware.conf

# /etc/lirc/hardware.conf
#
#Chosen Remote Control
REMOTE="SIR IrDA (built-in IR ports)"

# Arguments which will be used when launching lircd
LIRCD_ARGS=""

#Don't start lircmd even if there seems to be a good config file
#START_LIRCMD=false

#Try to load appropriate kernel modules
LOAD_MODULES=false

# Run "lircd --driver=help" for a list of supported drivers.
DRIVER=""
# If DEVICE is set to /dev/lirc and devfs is in use /dev/lirc/0 will be
# automatically used instead
DEVICE="/dev/lirc0"
MODULES="lirc_dev lirc_sir"

# Default configuration files for your hardware if any
LIRCD_CONF=""
LIRCMD_CONF=""

Help!! Anyone???

I've found out that the IR interface of the chipset is listed as PNP Device (WEC1020) under device manager.

Ubuntu Device Manager Details:

The windows driver states:

Any ideas?

Hi Sokairyk

Did you make any progress with this? Would be cool to have it working!

Unfortunately I think that the lirc_sir module does not support this chipset...

If anyone with similar problems has a solution it would be great to post it

Yesterday i had the cir working!
You need to build and install lirc from the latest cvs.
In this discussion you can find some other details.
Sorry for bad english
