Vijay, thanks a lot for your answer. Of course you're not wasting my time!
The thing is that I've been using OpenBSD only on a virtual machine,
while I get ready to install it on my laptop. I was just making sure
that everything works fine.
The revision I'm using is the number 1. Maybe the driver works, I just
used a USB to run the installation program and check if the network
interface was detected, but it didn't; that's the reason why I say the
driver probably doesn't work. I also have a wireless usb device
(D-Link DWA-110) and when I plug it in it loads the appropriated
driver and creates the interface (rum0). I was expecting the same
happen with my Broadcom.
Should I do something else to get my BCM4312 working?
