I got the Broadcom 4312/4313 Hybrid Bluetooth + Wi-Fi working with Kernel 3.0.4 and the Broadcom STA driver.

Hybrid chips are a pain to get working but they do work.

Try this to get these devices working:

1. Remove any firmware or drivers you may have installed beforehand.

2. Build and install kernel 3.0.4 (make sure you double check the configuration for Broadcom wireless modules and Bluetooth modules)

3. Build and install Broadcom-STA and create a symbolic link to the wireless folder in the modules.

4. Blacklist the ssb and b43 drivers.

5. Do NOT edit any config files anywhere in the system and use WICD to control the wireless card.

Word of warning... if your router supports the protocol for DNSMasq and DHCPMasq you MUST turn them off or the wireless card will not connect.

But BCM4313 is not recognized by b43, and it's not ssb based; so there's no need to blacklist those drivers.

From kernel >=2.6.38.x you can install it's FOSS version with brcm80211, by selecting it on staging drivers, if you'll compile your own kernel. The only extra thing that you'll have to do is to download the firmware, which is available at the kernel-git-repository - http://git.kernel.org/?p=linux/kerne...x-firmware.git - because it's a propetary firmware, and cannot be bundled on the kernel-source tree. At this site - http://linuxwireless.org/en/users/Drivers/brcm80211 - there's all one needs to know about this driver.
