I'm running 2.6.24 with Freescale's lite5200 as my base. I'm interested
in this USB adaptor for wireless USB, but my web search does not make me
confident that my effort will yield fruit.
Can anyone direct me to a good source outlining success stories with
wireless USB adaptors? At present I'm mesing with Linksys WUSB54GC and
some driver source from Ralink, but my cross-compile is not working.
I'll keep wrestling with it, but please offer some advice if you can.
Thanks!

I just turned on all wireless drivers in my mpc5200 build and they all
built ok. I'm using Linus' current git tree.
rt2501 (WUSB54GC) is in the current kernel.
AFAIK these should work. Some times there are minor problems with
endianess but they aren't hard to fix. The usual error is loading the
firmware byte swapped.

Umm, the WUSB54GC is not a "wireless USB" adapter. It is a USB WiFi
adapter. If you're looking for wireless USB then it is the wrong
device.
If you are looking for a suitable wifi adapter, then that device
should work, but if you can go with a PCI or a miniPCI WiFi adapter
instead then you should get better performance. The 5200 only has USB
1.1.
I'm having good success with an Atheros miniPCI adapter at the moment
using a 2.6.28 kernel.

Thanks. Yes, USB wi fi is what I'm after. I did find the driver I
needed after enabling the WLAN80211 and EXPERIMENTAL options. The device
discovery appears to work, and with wireless tools I can iwconfig and
see my interface.
QUESTION: when I "ifoncfig wlan0 up" it results in an attempt to load a
firmwmare file as follows. as you can see, it fails. What are these
firmware files? I can't find it in my build output. How do I build it or
where do I get it? Where would I put it on my target?
I did search for answers to these questions and tried to stick an
rt73.bin of unknown origin (to me anyway) in /lib/firmware but I got the
same error.
-sh-2.05b# ifconfig wlan0 up
[ 2212.027071] phy1 -> rt2x00lib_request_firmware: Info - Loading
firmware file 'rt73.bin'.
[ 2272.058793] phy1 -> rt2x00lib_request_firmware: Error - Failed to
request Firmware.
SIOCSIFFLAGS: No such file or directory
Thanks again,

Thanks Jon. I'm still struggling with this rt73.bin issue. My 2.6.24
Kconfig presents options slightly different from what you describe
below. I've tried a few different settings and I placed the rt73.bin you
sent me under /lib/firmware.
I'm still getting the "failure to load rt73.bin" error on "ifconfig
wlan0 up".
my "generic" Kconfig options read as follows. I'm not sure if/what
option maps to, "include in-kernel firmware blobs in kernel binary"
Could this be a udev issue?
(/sbin/hotplug) path to uevent helper
? ? [*] Select only drivers that don't need compile-time external firmware
? ? [ ] Prevent firmware from being built
? ? {*} Userspace firmware loading support
? ? [ ] Driver Core verbose debug messages
? ? [ ] Managed device resources verbose debug messages
I'll keep trying different things, but if you can provide additional
guidance I will appreciate it very much. Thanks again.

I received great help last week in getting a USB wi fi device working.
Thanks again, but can someone read below and advise me on kernel 2.6.24?
The best out-of-the box solution for me was 2.6.27.8, for which I needed
a Denx eldx toolchain in place of the toolchain I was using to compile
2.6.24. The significance of all this is that I did get USB wi fi
working, but...
I'm not in a position to upgrade from 2.6.24 at this time. I need to get
the USB wi wi (Linksys WUSB54GC) working under 2.6.24.
After success with linking firmware with the 2.6.27.8 kernel, 2.6.24 I
keep hitting this error when loading from user space (I don't appear to
have the, "link with kernel" option with 2.6.24)...
sh-2.05b# ifconfig wlan0 up
[ 764.744354] phy0 -> rt2x00lib_request_firmware: Info - Loading
firmware file 'rt73.bin'.
I have spent many, many hours following leads (and links) this group has
directed me to. I've done the following...
1)placed rt73.bin in various locations (/lib/firmware,
lib/firmware/'uname -a', and the location specified by my
/etc/hotplug/firmware.agent)
None of this appears to make a difference.
2) I'm a bit confused by the hotplug dependancy, although I do have
hotplug enabled. "hotplug" makes me think I should be configuring some
script to load the firmware upon device insertion, but, "ifconfig wlan0
up" appears to want to load the firmware anyway so I'm guessing if I
just get rt73.bin in the right spot it should work.
Comparing my working 2.6.27.8 to 2.6.24 in the areas of "firmware: and
the ralink rt2x00 drivers reveals MANY changes, no doubt for the better.
QUESTIONS:
1) Am I missing something VERY simple on this firmware loading topic
that should make this work under 2.6.24, or am I bumping into the reason
so much of this code has changed between 2.6.24 and 2.6.27.8?
2) am I correctly, "installing" the firmware just by placing rt73.bin in
the correct location in my filesystem, or is there some other magic
required before, "request_firmware()" will work?
Just when I thought I understood some of the kernel I hit a new topic:
firmware loading! Any help much appreciated...
