Re: rt2x00 driver

2007/4/9, Rafael EspĂ­ndola <rafael espindola gmail com>:
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: rt73usb - CVS (N/A) by http://rt2x00.serialmonkey.com.
usbcore: registered new interface driver rt73usb
Loading module: rt2500usb - CVS (N/A) by http://rt2x00.serialmonkey.com.
usbcore: registered new interface driver rt2500usb
wmaster0: Selected rate control algorithm 'simple'
Ralink usb devices can use rt2500usb or rt73usb (you "may" need to
uses rt71w-firmware currently in review with the second case!). The
first step should be to blacklist one or the other doing: echo
"blacklist rt2500usb" >> /etc/modprobe.d/blacklist
iwlist works despite the warning:

iwlist wlan0 scan
Same result with my rt2500pci, the problem is association is failling.
Sometime you can have better result using rausb0 or ra0 aliases...
(this has been rapported sometime - not my own experience...)
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...
Same warning! But since this may prevent to associate correctly with
Ralink's devices we should consider this as a bug!
I have the latest wireless-tools installed. Should I recompile it?
The Wireless-tools from devel is tha same version as Fedora Core 6,
this is a problem because this site:
do not mention WE-22 but beta WE-21, and i down't know where can i
find tools that supports WE-22 (any link or references?)
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...
This implies that wpa-supplicant may be updated, i'm only working on
hostapd for now and i  didn't received answears for this bug,
requesting it: https://bugzilla.redhat.com/230857
This was before the 80211 stack named change (from d80211 to mac80211 ).
But since i didn't recevied any answear may we consider this package
as orphaned ?!

Rafael if you could test hostapd it would help, but for now the
package isn't ready for inclusion in my view (mostly because of
headers not in kernel)...
I will try to work on wpa_supplicant update unless someone take it...

Also i've read some link from ivd the main dev for rt2x00 who said
that rt2x00 do not seems to be ready for 2.6.21. But solving all
theses issues may help to have working wireless mac80211 devices "out
of the box" (dreams)

Some references :

I was working on legacies version for some time now but they are going
more bad each day...The paradox is that thoses devices are privilegied
by FSF because of legal conformity with GPL...
