Hi all:
I'm trying to use my USB IRDA dongle on my Arch machine.
I've installed irda-utils package from AUR.
When I insert the dongle i see that the module mcs7780 is loaded, but no device appears on /dev.
If I do lsusb -D /dev/bus/usb/003/005, I get:

I don't know if I need to configure it using irattach or if I need to adjust any config files...
If I plug it on a Debian/ubuntu/Mint box, the light on the dongle immediately starts flashing.
Does anyone have any ideas on where should I start troubleshooting this?
Cheers:
Pedro

Solved.
One needs to run: sudo irattach irda0 -s
Hope it helps someone ;-)
