I just have a few comments...
1) There is more USB-IrDA devices than those you list in the
driver, and most IrDA-USB devices don't follow the spec in some way or
another. Please check .../drivers/net/irda/irda-usb.c for the gory
details...
2) The idea is great, but I think the overall architecture
could be improved. The way you have done it leads to code duplication
(irda-usb.c + ir-usb.c) and work only for a small subset of the IrDA
devices (i.e. don't for for other FIR devices such as NSC, SMC, ALI,
SigmaTel-USB...). The API of IrDA driver is simple and well defined,
so it would be IMHO much more efficient to do a simple TTY wrapper
that would work over *any* IrDA driver. I think that LIRC is moving
this way...
3) The Linux-IrDA stack already allow you to talk to embedded
devices with no IrDA support. This is called the Ultra protocol (very
simple, no handshake, no management frames). I can give you some
examples if you want...
Have fun...
