	Hi,

	First thanks for Dag for bringing me into the conversation. I
may add my little bit of spice, especially that I was the one pushing
for having the driver in .../drivers/net/irda.
	By the way, Greg, sorry if I hurt your feeling, I don't want
to put down any of the great work that has been done on the USB stack.

	My feeling is that devices are mostly defined by their higher
level interface, because this is what is closer to the user.
	If I look at a Pcmcia Ethernet card, I will tend to associate
more with a PCI Ethernet card rather than a Pcmcia SCSI card. Both
card have the same high level interface (TCP/IP) even if their low
level interface is different (Pcmcia, PCI).
	People tend to agree with that, and that's why you have
directories called drivers/net, drivers/scsi and driver/sound, rather
that drivers/pci, drivers/isa, drivers/mca and drivers/pcmcia.

	If I get an IrDA-USB dongle, the feature that matter the most
is that it does IrDA, the fact that it connect to my PC via USB is
rather secondary.
	That's it. I hope it explain some of the rationale and why we
departed from the usual drivers/usb arrangement. Actually, I think
that stuffing all USB drivers in drivers/usb is not that great, but
that's not my call...

	Have fun...

	Jean
