rt2x00 driver

[Rafael Espíndola]

I am having problems with the rt2x00 driver present in the kernel
3045. I have an usb device (Belink f5d7050, fcc id: k7s-f5d7050b).

When I plug the device the driver loads correctly:

usb 5-1: new high speed USB device using ehci_hcd and address 7
usb 5-1: configuration #1 chosen from 1 choice
Loading module: rt2x00lib - CVS (N/A) by http://rt2x00.serialmonkey.com.

Loading module: rt2500usb - CVS (N/A) by http://rt2x00.serialmonkey.com.
usbcore: registered new interface driver rt2500usb
wmaster0: Selected rate control algorithm 'simple'

iwlist works despite the warning:

iwlist wlan0 scan
Warning: Driver for device wlan0 has been compiled with version 22
of Wireless Extension, while this program supports up to version 20.
Some things may be broken...

I have the latest wireless-tools installed. Should I recompile it?

The problem starts when running wpa_suppilcant:

/usr/sbin/wpa_supplicant -B -i wlan0 -D wext -c /et plicant/wpa_supplicant.conf
ioctl[SIOCSIWMODE]: Device or resource busy
Could not configure driver to use managed mode
ioctl[SIOCSIWAUTH]: Operation not supported
WEXT auth param 4 value 0x0 - ioctl[SIOCSIWAUTH]: Operation not support

Does someone knows what is wrong? What version of rt2x00 is included
in the kernel? Do think I should compile a new version? Should I add
the dscape patch to wpa_supplicant? According to the rt2x00 site newer
versions should work with the wext driver...

Thanks,
Rafael
