Oh, thanks! That was the problem after all. I was reading the logs
incorrectly.
With the corrected setup packets, I was able to start discovery with
irattach (as seen with wireshark). The name of my cellphone shows up
correctly, so far. However, once I try to obexftp -i -l (list directory
over IrDA transport with OBEX), my machine crashes hard... I think it is
because I violated the rule that states that usb_control_msg() "cannot
be called from within interrupt context or with a spinlock held" ... and
I use it to implement speed change. Nothing I cannot fix overnight at home.
Thanks again!
