📡 Getting the Fintek IR receiver to work with Linux

21 Nov 2015

Some of the Medion AIO (all-in-one) desktop pc-s are equipped with IR remote receiver, which doesn’t work out of the box on linux. Instead during boot it gives the following error:

[    6.925985] fintek-cir 00:06: IR PNP Port not valid!

Quite annoying, but here is a workaround for it. It’s not really a fix, because the error message still appears at boot, but the IR receiver is going to work afterwards.

Unload the module called fintek-cir:
```
modprobe -r fintek-cir
```

Fix the drivers IO mapping:

echo "auto" > /sys/bus/acpi/devices/FIT0002:00/physical_node/resources

Re-load the module fintek-cir:
```
modprobe fintek-cir
```

That’s it, the IR receiver should work now. You can check the tail of dmesg to make sure it’s fine. Now to automate this process at boot, the following steps were necessary:

Create a file with the following content:

#!/bin/sh
/sbin/modprobe -r fintek-cir
echo "auto" > "/sys/bus/acpi/devices/FIT0002:00/physical_node/resources"
/sbin/modprobe fintek-cir

Save it somewhere, like /etc/fintek-cir.sh.

Mark it as executable:
```
chmod +x /etc/fintek-cir.sh
```
Add an entry to the crontab (root):
```
@reboot /etc/fintek-cir.sh
```

The receiver should work after every (re)boot, LIRC can be installed now.
