When I insert this USB IrDA device, I hear the computer get busy. I notice
that the following populates via "lsmod|grep stir":
stir4200 13637 0
irda 121469 1 stir4200
I manually seek out what would be the logical device, yet I find no device
under /dev. I execute the following "lsusb -v -s 001:003" and get:

I execute "dmesg|grep ird" with some success:
divert: not allocating divert_blk for non-ethernet device irda0
drivers/net/irda/stir4200.c: IrDA: Registered SigmaTel device irda0
divert: no divert_blk to free, irda0 not ethernet
divert: not allocating divert_blk for non-ethernet device irda0
drivers/net/irda/stir4200.c: IrDA: Registered SigmaTel device irda0
So is this thing supposed to attach to some device node irda0 ?? I can't find
it. How should I approach this differently? Am I supposed to make a node?
Also, how is one supposed to know where the heck a usb device attaches
itself?
"ifconfig irda0" says this:
irda0 Link encap:IrLAP HWaddr 00:00:00:00
NOARP MTU:2048 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:8
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
I hope I can still use this thing as a remote control device. That's why I
bought it.
