Hello Arnaud,

I read the page http://linuxwireless.org/en/users/Drivers/b43 to
see what I could do and if this (porting the driver to FreeBSD) is
something matching my knowledge...

My chip says:

none2 at pci0:1:0:0:       class=0x028000 card=0xe01b105b chip=0x431514e4 rev=0x01 hdr=0x00
    vendor     = 'Broadcom Corporation'
    device     = 'BCM4310 USB Controller'
    class      = network

I understand this as PCI-ID 14e4:4315 and 4315 seems to be supported by
Linux b43 driver. But, on the other hand the page says: 

    Caveats
    ...
    If you have an Broadcom USB device, please use the rndis_wlan driver.
    The b43/b43legacy driver is not meant to support this device.
    ...

So I'm not sure. Or is the above string "BCM4310 USB Controller" just
because the FreeBSD kernel does not detect the chip correctly.

Thanks
