That combination of outputs and the -EBUSY (-16) error means that the driver was 
unable to read or write a configuration variable at SSB_PCMCIA_ADDRESSX, where X 
is 0, 1, or 2.

There is a possibility that your card is broken. Please post the portion of the 
output of the command 'sudo lspci -nn -xxx' that describes the b43 device.
