But opensuse cannot auto-detect this USB wireless adapter in “Network setting”

What can i do??

you need rt73.bin file with Ralink USB WLAN sticks. Get it from the Ralink site here:

RALINK SOFTWARE END USER LICENSE AGREEMENT

Then drop the rt73.bin file into the folder /lib/firmware and that should get you going. I have a D-Link USB stick DWL-G122 and that’s all I needed to get mine up and running.
