IrDA isn't something easy to set up. It took me some months to finally
get it working.

There are others, apt-cache search irda will give you a list. Not all
are needed, though.

Here's what I answered when installing irda-common :
% debconf-show irda-common
* irda-common/ttydev: /dev/ttyS1
* irda-common/aboutdoc:
* irda-common/enable: true
* irda-common/changes:
irda-common/mkirdev:
* irda-common/discovery: true
* irda-common/regen: false
* irda-common/dongle: none
* irda-common/firdev: smc-ircc
* irda-common/firopt:
* irda-common/selectdevice: serial
The device (ttydev) to use is the _serial_ device on which the IrDA
port is attached, so that would be /dev/ttyS1 and not /dev/ircomm0
(that you should use when you want to reach a device over the IrDA
link).
Run "dpkg-reconfigure irda-common" to change the configuration of
irda-common, then restart the irda service.

Use ps to see what options where passed to irattach. You should find
the serial device (/dev/ttyS1) and the discovery option (-s).

Yes, I've had this problem, however, I no longer experience that with
2.4.22-ben2 and an up-to-date unstable system (dunno which of the
kernel or userspace tools changed, but that doesn't happen anymore).

I think this is because of the wrong device setting.

Hope you'll have more luck this time...
