Jouni (and all),

(I'm soooo close.....)

The SDK is irrelevant. I tried compiling it on my Ubuntu workstation (9.10) but the compile broke at the same place. I commented out CONFIG_DRIVER_NL80211 to get it to build successfully. I have no idea if that's OK or not to do as there's no technical descriptions on what linux components I need and how they all work together. (BTW, any pointers to such would be appreciated)

Now that the supplicant is built I'm trying to get some basic functionality going with the supplicant on my embedded platform. I tried to get the supplicant to do a simple scan but it's working ever so intermittently. I have better luck using the command 'iw dev wlan0 scan', however even this command will only work once, then nothing is returned after the same command is re-issued. To get it to work again I have to shutdown the interface and then bring it back up. After that the 'iw' scan command will work again once or twice.

The wpa scan command however hardly works at all. I only got it to work twice in a row at one point, but that's it. I do always see the leds blink on my USB wireless adapter (D-link WUA-1340) every time I invoke the wpa scan command so I know the supplicant is talking to the device.

To do a scan I kept it simple by following the instructions for operation without a configuration file in the README, so that I can eventually work towards full operation with a configuration file. Here's a summary of commands I used with it's output when I did manage to get a wpa scan to work:

=============================================================

When the wireless USB device is plugged in, hotplugging reports that the device is using built-in firmware.
   "rt73usb 1-1:1.0: firmware: using built-in firmware rt73.bin"
Could the firmware in the USB device be out of date? How can I expose its version? How can I get the device to upgrade?

Appreciate any help?

thanx
