I've HP Compaq 6715s laptop. I'm trying
to get wireless working. The laptop has
Intel 4965 4965AGN wireless WiFi PCI-E card 802.11N AGN
which is supported by iwn(4). I compiled iwn support
into the kernel as suggested by the man page.

However, the card doesn't appear in dmesg or
in pciconf -lv.

The laptop has a wireless toggle button, which is supposed
to enable/disable wireless. There is also an LED, which
lights on when wireless is enabled, and goes off
when wireless is off. Well, at least this is what
should happen.

On boot the LED is on.

If I press the button to disable wireless, the LED goes
off and in dmesg I see:

ugen0.2: <Broadcom Corp> at usbus0 (disconnected)

When I switch wireless back on again I see in dmesg:

ugen0.2: <Broadcom Corp> at usbus0

Does this mean that wireless sits on USB bus?

Does this give me a clue about how to debug
the problem further?

many thanks
