Hi Rob,
Have you tried setting the option (under "Advanced") "Plug & Play OS" to "No"?
I found that all the interrupt assignments went screwy under Linux without
this, and particularly the USB support in the backport wouldn't work.
Second thing is that I used to get the "Wrong chip version 0c" message with
the irda-utils-0.9.5 which is distributed with Debian 2.2 (was "unstable", now
"frozen" - otherwise known as Potato). If you uninstall those packages
with 'dpkg --remove irda-tools irda-common' and then build and use
irda-utils-0.9.9 from the latest snapshots it works on my Vaio. I just
copied irattach and findchip and a few other interesting things into my
/usr/local/sbin after building for now.
Heres as many relevant details as I can muster from the BIOS of my N505X. I'll
send the kernel config I used to you directly, as its not interesting enough
for the list.
Mail me if there are any other details I can send to you direct.
Good luck,
Simon
