The b43-pci-bridge driver is a wedge between ssb and the drivers b43 and b43legacy. It is the part of the system that decides if your bcm43xx hardware needs the new b43 driver, or b43legacy that handles older hardware.
Your system was not loading b43 because the patch that allowed the system to recognize that device was reverted in the middle of the Hardy testing process due to a report that it broke a BCM4312 device. A new patch that should enable your device and not break the 4312 has been submitted to the Ubuntu Kernel Team. -- b43 driver ignores BCM94311, regression https://bugs.launchpad.net/bugs/222343 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
