That is completely unrelated. You plugged in a USB device too :)
No, it's my "bluetooth + wlan" device. Note that disabling wireless with 
the hardware switch also gives 'usb 3-1: USB disconnect, address 2'.

Ah :) That's just bluetooth then though, not wifi.

A lot uglier with those errors. And after that I have to run
ifdown/ifup before networking is up again (ifup only does not work as
it will complain "interface already configured"):
And that's actually expected, and/or a bug in the debian networking
scripts.
(You can trigger the same problem by doing
ifup wlan0
ip link set wlan0 down
ifup wlan0 -> error)
OK, I can accept that. Wonder why it does work with 2.6.30 then. But it 
can certainly wait until the driver problem you mentioned is resolved.
2.6.30 didn't have the "ip link set wlan0 down" on rfkill behaviour, but
overall that makes life for everybody (except people who actually use
ifup/down) much easier.
