Tnx novsan…I try the rt3070sta driver. Why Ralink not make a list of devices and there relating drivers? Or does this exist?
When I plug in the usb device it automatically loads rt2800usb and his dependencies. And after it gives a message from a function that the wrong chipset is detected.
They better leave it out the kernel, so we can load or drivers manually. 
Hope a find a nice driver now. This DWA-140 is a very recent device.
ralink made chip, dlink made device. Dlink have not official linux support for this device…
Just advice:
uname -r
You have 2.6.31.5-0.1-desktop kernel version,so download rt3070sta-kmp-desktop package from here:Index of /repositories/driver:/wireless/openSUSE_11.2
If you have updated kernel version - download package from here:Index of /repositories/driver:/wireless/11.2-update
Install this package usual way with rpm command.
4 Restart your machine and plug adapter again.
5 Check wireless interface with iwconfig command.
Good luck!
After installing the rt3070sta rpm, I cant c the module loaded in the kernel.??
The good thing is, I now have the good driver.
The ID list resite in usb_main_dev.c .
Did you install right rpm? Seems that st3070sta-kmp-.rpm require st3070-common-.rpm. Did you install it too?
please check you packages:
rpm -qa | grep st3070sta
Sorry, i’ve confused by first line. Did you solved problem?
Yes, the /desktop rpm. And now I installed the /common too.
Package check is ok. I get no errors there.
Do I need to load the module manually?
You need to blacklist rt2800usb,rt2x00usb,rt2x00lib,rt2870sta modules.
Remove usb dongle and reboot. Insert adapter again and check your wireless interface.
rt3070sta driver should be in the /lib/modules/$(uname -r)/updates/ directory
I blacklisted all the other modules. /Updates/ folder not found.
You can’t find /lib/modules/$(uname -r)/updates/ directory? So, you didn’t install correct version of rpm packages.
please check kernel version
uname -r
2.6.31.5-0.1-desktop version. I downloaded the desktop rpm and the common rpm…
These rpms?
rt3070sta-common-2.1.2.0-1.1.i586.rpm
rt3070sta-kmp-desktop-2.1.2.0_2.6.31.5_0.1-1.1.i586.rpm
If they are correct, try to reinstall rt3070sta-kmp-desktop-2.1.2.0_2.6.31.5_0.1-1.1.i586.rpm
rpm -Fhv rt3070sta-kmp-desktop-2.1.2.0_2.6.31.5_0.1-1.1.i586.rpm
Yes, those 2. 
I get a key warning: Header V3 DSA signature: NOKEY, key ID 4073bdbe.
It’s allright.
Does the package load the module automatically?
I expect that you already have rpms installed. And you have blacklisted rt2800usb,rt2x00usb,rt2x00lib,rt2870sta modules.
check is there blacklisted modules in memory:
lsmod | grep rt2800usb
lsmod | grep rt2x00usb
lsmod | grep rt2x00lib
lsmod | grep rt2870sta
if any of these modules is loaded into memory - unload them with rmmod command.
Unplug and connect adapter again.
Check rt3070sta module in memory:
lsmod | grep rt3070sta
If module didn’t loaded - try to load it with
modprobe -v rt3070sta
check wireless interface with
iwconfig
novsam… Still no interface in the list?
Think I go digg deeper in the code and the mechanics of this module and firmware.
In_Control01, rt3070sta is driver for your device - look here: [SOLVED] rt3070sta: module license ‘unspecified’ taints kernel. - Linux Forums](http://www.linuxforums.org/forum/wireless-internet/161550-solved-rt3070sta-module-license-unspecified-taints-kernel.html) post #2
See output of dmesg command.
I dont get those errors. Probably they fixed that in the package already.
When I try to build the rt3070sta I get more ‘Unknown symbol’ errors.
Do you using your self-compiled driver? Or from rpms?
Do you install rpms and using your self-compiled driver? 
I use rpm’s… Cause mine dont build yet without errors.
So mine can’t be loaded yet.
