Indeed. That has been my long-term thinking about IRDA - most of the
IRDA dongles are just USB or serial devices, and the protocol
could/should be done in user space.

That's particularly true for something like a divecomputer, which
really only talks to one single device.

IRDA in _general_ is really damn complicated. And nobody actually does
the general case.

So the sane thing to do would be to basically do a special custom IRDA
thing that just talks directly to the dongle (using libusb, or just
using a serial port, depending on what the uwatec dongle actually
