Dear Michael and Stefano,
I have a project which integrate Broadcom Wifi chip. But the mainline b43 still does not support this chip, because it has Low Power PHY.
Here is my lspci -vvnn output for this device:

Do you guys know how to support this device in 2.6.31 kernel? Need I backport some code from wireless-testing? I enabled the PHY_LP config manually in 2.6.31 kernel and b43 driver recognized the hardware wifi device, but it still
does not work at all.
Or there is no choice but Broadcom's STA driver? I do not like such non-GPL stuff.
Thanks a lot

OK, got you. Thanks. I'm just wandering how to debug this driver. It seems that probing passes but the wlan1
interface does not work at all.

Try disabling QoS via modparam. Also, try earlier compat-wireless versions.

Use "sudo iw dev wlan1 scan" with mac80211 drivers.

I have noticed that there is no notification of the radio switch being
off with the 4315; however, the radio is killed by the switch.
If I have time, I'll look at it, but I'm going to be travelling for 8
days and may not have much time.

Are you absolutely sure your radio switch is on? On my computer, the
driver is not reporting when the switch is off for the 4315 devices.

OK, do you know where can I find this firmware? I just followed the wiki page to get the firmware, but it seems the same version as I am using.

Yeah, I disabled the QoS via qos=0 modparam, but the result it is the same.

Hi Gabor,
I tried the latest cmpat-wireless 09-16 snapshot on my machine which runs on 2.6.31
Ubuntu Karmic latest kernel. The hardware probing passes and wlan1 interface shows up.
But the iwlist scanning got no data from wlan1 interface,
dmesg:

Do you guys think it is related to 64bit DMA issue? I really want to help to develop this b43 opensource driver,
anything need me to do, please feel free ping me.
Thanks

Try to enable mac80211/cfg80211 debug messages. Also enable SSB
debugging. (If mac80211 debugging is on, then you are hitting a
{mac|cfg|nl|lib}80211 bug, as your dmesg should contain entries like
"device is no longer idle".)
To Larry: Software RFKILL is not yet implemented for LP-PHY - it is
part of my calibration patch, which had other errors (software RFKILL
is a prereq for calibration). Feel free to split it out into a
separate patch if anyone needs it - I can't do it right now; no
working Linux system (due to the vmware problem).

Not an issue with 64-bit DMA. Those people with 64-bit DMA problems
get error messages.
Larry
This chip works (though not quite "supported", that is, can't
guarantee that it will work for you, and speed is not up to par with
wl_hybrid) in wireless-testing. It should also work in
compat-wireless, though compat-wireless is having problems with 64-bit
DMA lately (probably also affects the G-PHY 4311/02). Specifically,
the Dell 1397 (half-mini version of the 1395) and the HP 459263-002
are known to work.
