Hi David!

It seems you're out of luck right now:
http://www.linuxwireless.org/en/users/Drivers/b43#unsupported

But don't worry about .exes. Most of them are .zip or .cab files, and the other
ones can be extracted with the 'unshield' package.

Good luck!

So, would this mean that the device is actually supported? It seems to
be at least partially supported at
http://wireless.kernel.org/en/users/Drivers/b43

What would be my next step?

Well, the above only means that older versions of the PCI database had a
mistake in the device description. If you correct your own database by
running "update-pciids" as root then you should also see the correct
description the next time you run "lspci". At least we know now for sure
that you do have the 14e4:4315 (from what you posted in your other
message).

As I wrote in my earlier mail, the b43 uses a mechanism for identifying
supported devices that does not rely on the PCI IDs, and I unfortunately
do not know the details of how this "Sonics Silicon Backplane" subsystem
works.

> It seems to be at least partially supported at

Indeed, it says that 2.4 GHz is supported for the BCM4312, and 802.11 b
and g are both based on the 2.4 GHz band AFAIK.

> What would be my next step?

I would try to load the module and check the syslog for messages, i.e.

modprobe -v b43

grep -i b43 /var/log/syslog

If your computer loads the module and then complains about missing
firmware then you know what you have to investigate next.

If your computer loads the module and produces another error message
then you have something to feed to Google and hope for the best.

If your computer loads the module without error message but does not
create a wireless device node (check with /sbin/iwconfig) then you may
have to try going via ndiswrapper as has already been suggested earlier.

In any case it is probably a good idea to post here what you get from
the syslog; maybe somebody else will have a better idea about what is
going on.

Looking at drivers/ssb/main.c, I think there has to be something like
this in the syslog when the ssb module is loaded:

Sonics Silicon Backplane found on PCI device 05:00.0

Do you see such a message? If it is absent then the SSB bus is not
recognized on your device.

I am not too optimistic now, because I found a MODULE_DEVICE_TABLE in
drivers/ssb/b43_pci_bridge.c which does not include your PCI device ID.
You could try to "modprobe b43_pci_bridge" if it is not loaded already,
but this is grasping at straws.

The general PCI ID table lists two different BCM4312 wlan adapters; it
seems that currently only the one with the device ID 0x4312 is
supported, while yours with the device ID 0x4315 is not.

Check out this link dealing with ndiswrapper:
