Re: any luck with wireless USB adaptors?

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.

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?
    

Kconfig
Device drivers
  generic driver options
     user space firmware support
        check - include in-kernel firmware blobs in kernel binary

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,
Mike

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.

        

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.
