I    mixed    things   a   bit   up.   I   compiled   rtl8187   from   realtek
(http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=16&PFid=14&Level=5&Conn=4)
on SuSE 10.2.
But I found no source that compiles under SuSE 10.3 which has a kernel > 2.6.19 where there is no config.h any more. So I used rtl8187-kmp-default-20070806_2.6.22.5_31-2.i586.rpm from ftp://ftp5.gwdg.de/pub/opensuse/distribution/10.3/repo/oss/suse/i586/ which was recommended in a thread concerning micronet USB-WLAN as well (which SP907 was'n mentioned). I also installed rt2x00... from the SuSE DVD. compat-wireless-2.6.tar.bz2 did not compile, which I thought would be the best choise.

I'm  not sure if it is possible at all to switch to a different kernel version
in SuSE but I'll give it a test on my LFS-laptop.

What's it for the wmaster0? Do I have to configure it as well?

This seems to be the problem. It does not catch the channel  of  my  WLAN  nor
does it help to set the frequency directly.

Yes WEP for the time I'm here at my parents house because (though less secure)
my good old flashed orinoco card seems not to be able to handel WPA. The Stick
is supposed to be abled to do both WEP and WPA.

No,  scanning  doesn't work either. Also "ifconfig wlan0 up" takes a long time
to finish  compared to other devices I have worked with. It yields the "wlan0:
link is not ready" message.
iwlist wlan0 scan gives: wlan0 No scan results

I tried both an none worked.
Is  it  possible,  though  the  driver  catches the device and I don't get any
error-messages, that the Stick cannot be used under linux?


Thanks for any further help or hints
