: Nope :( It does not work. I applied patch to /sys/dev/sio/sio_pccard.c
: and recompile my kernel with NEWCARD. It seems devd pays no attention
: when i plug or unplug the 3COM card. I have attached dmesg output and
: my devd.conf file. I was trying to get devd to kldload ng_bt3c module,
: but it did not work. Am i missing something obvious here?
Yes. You need to have ng_bt3c loaded before you insert the card.
That's because of three reasons:
1) We don't detach a device when it 'won' the bidding on the device
with a bid < 0 when a new driver is loaded.
2) There device is known, so devctl doesn't report anything to devd
because it is known (it will report the sio attach).
3) devd ignores all unknown devices at the current time.
I'm working on most of these issues, but not the 'rescan' issue.
