[rt2x00-users] Problem loading wlan0 interface with Edimax EW-7318USg (rt73usb module)

Mon May 25 15:32:22 CDT 2009

Hi,

I've compiled the latest 2.6.29 kernel for the BeagleBoard 
(http://beagleboard.org/ , ARM architecture, Debian), and included 
rt73usb as a module.

The module seems to load fine without warnings:

[ 1317.364959] usb 2-1.2: device v148f p2573 is not supported

[ 1318.171875] usbcore: registered new interface driver rt2500usb

but when I issue 'ifup wlan0', the module keeps producing these errors 
(repeatably):

Can anyone identify what the problem is? How should I proceed?
I should note that the dongle is working fine in my PC (AMD64 2.6.29 kernel).

Thanks,
       Lior.
