Reading the sprom did not worked. This is probably a BCM43224 OTP, for
which support was added in kernel 3.4 to bcma.

You device should be supported by b43 and brcmsmac. Please try out at
least kernel version 3.4 or a corresponding compat-wireless version.
There is also a ubuntu package named
linux-backports-modules-cw-3.4-precise-generic which contains a more
recent compat-wireles version.
