Hi,
I have a Dell usb wireless card that I am trying to use under Linux.
A search of the FCC-ID M4Y-XG705A lead me to believe it has a Z-Com
XG-705A chipset. Another search tells me that the p54usb driver
should work. So I added
{USB_DEVICE(0x413c, 0x5513)}, /* Dell Wireless */
to the /usr/src/linux/drivers/net/wireless/p54/p54usb.c file in the
correct spot. A quick recompile and the module was built. I did a
modprobe p54usb and dmesg shows:
cfg80211: Calling CRDA to update world regulatory domain
usbcore: registered new interface driver p54usb
cfg80211: World regulatory domain updated:
(start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp)
(2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)
(2457000 KHz - 2482000 KHz @ 20000 KHz), (300 mBi, 2000 mBm)
(2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm)
(5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)
(5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)
However iwconfig doesn't list a wlan0. OK maybe I need firmware so
another search leads me to
http://wireless.kernel.org/en/users/Drivers/p54 where I download
2.13.24.0.lm87.arm (USB 2nd generation (ISL3887)), rename it to
isl3887usb and put it in /lib/firmware. I rebooted and still no wlan0
listed in iwconfig.
What did I do wrong?
Thanks,
Greg

Please post the diff, so it can be integrated into -stable!

have you put the newly-built module into the right directory?
modprobe only takes modules from the kernel's module directory
(which is normally /lib/modules/$KVER/kernel/...)
you can verify that by calling modinfo p54usb and
check if there's a line usb:v413Cp5513d*...

please don't use "iwconfig". WEXT is obsolete, you can find a
nl80211 replacement "iw" right here:
http://wireless.kernel.org/en/users/Documentation/iw .

No need for a reboot, if the correct module is loaded the device
should be recognized instantly... (or as soon as it is replugged.)

I will have my friend post the diff tomorrow as I don't know how to make a diff.

You are right I was booting with the wrong kernel. The default was
2.6.34-rc5 not the 2.6.34 we compiled.

I have iw and it works. I just have to figure out how to use it :)
