What exactly do you mean by 4312? If you mean a PCI ID of 14e4:4312, then the 
firmware above is partially correct. The ucode5.fw is correct, but you also need 
b0g0initvals5.fw and b0g0initvals5.fw. In addition, you might need 
a0g1initvals5.fw or a0g1initvals5. I no longer have one of those devices, thus I 
cannot test.

If you mean BCM4312 802.11b/g, then your firmware selection is wrong. This type 
of device will have a PCI ID of 14e4:4315 and will require different firmware. 
For these LP-PHY devices, b0g0initvals13.fw, lp0initvals13.fw, and ucode13.fw 
are probably needed.
