A missing tty device node for an USB dongle.

I was trying to make my MA-660 infrared dongle to work today again, which is supposed to be supported by GNU/Linux although apparently not very easy to set up (as in plug and play), but something's wrong.

This thread nicely describes the process of setting it up to work and I did as it's shown there. It's not that much of a hassle. However, the /dev/ttyUSB0 node is not created despite me loading all the mentioned modules. When I unplug it and then plug it back in the only thing I get in /var/log/messages is:

Jul 12 03:03:20 procyon kernel: [53502.401685] usb 5-2: new low speed USB device using uhci_hcd and address 17
Jul 12 03:03:20 procyon kernel: [53502.617323] usb 5-2: configuration #1 chosen from 1 choice

So it doesn't detect it and attach it to a device node the way my USB modem does, for example. Why is that if I have the ma600-sir and other modules loaded? What else can I do for the device node to be created? It's the only thing missing here apparently.

Thanks

Is your distro using UDev?

Is your distro using UDev? Might it be possible that there are no rules to create these devices? Or rules that suppress creation of these devices?

Ubuntu Fiesty is using UDev

Ubuntu Fiesty is using UDev I believe, yes. However I'm afraid I don't know much if anything about how udev rules work. It sounds like it might be it but I'm not sure how to fix that.
