That requires the PCI ID in ssb's tables. You will also need a fairly recent kernel (2.6.26-rcX) if the devices have a 400 byte SPROM that is not rev 4. It may be necessary for b43 to be loaded, but theSPROM can be read even if b43 doesn't recognize the device.You don't need to load b43. Just modify ssb, load it and read the spromvia /sys/foobar/ssb_sprom -- Greetings Michael.
ok, got the new kernel (2.6.26-rc5) installed as recommended.
Booted machine with WMP300N installed and did the following:
_______________________________
sudo -s
uname -r
2.6.26.rc5-wifi-testing
modprobe b43
cd $(dirname $(find /sys/devices|grep sprom))
cp ssb_sprom ${HOME}/orig_sprom; # try using cp
ssb-sprom -i ${HOME}/orig_sprom -P
Corrupt input data (crc: 0xA9, expected: 0xFF)
rm ${HOME}/orig_sprom; # delete the file just in case
cat ssb_sprom > ${HOME}/orig_sprom; # try using cat
ssb-sprom -i ${HOME}/orig_sprom -P
Corrupt input data (crc: 0xA9, expected: 0xFF)

_______________________________The results are the same for the WLI-PCI-G300N and as far as I can tell they physically appear to be the same card.
I have verified by viewing the subsystem_device and subsystem_vendor files do contain the correct information for the installed card so I can confirm it is working to some degree, at least it's recognizing the cards.
As I said, I don't need the wireless lan to be functional, just the ability to read/write the sprom data at this time.
