Hi Frederic,

maybe it's the wrong place to ask, but did you get the work in converting the
original driver any further?
My problem is, i have an usb wlan stick using an realtek 8188su chipset. 
I used the (staging) driver for rtl8192su contained in the 2.6.33 kernel
on a amd64-mandriva system and included the usid of the stick, compiled
and installed.
Up to now, the stick is recognized, and scans the surrounding networks. 
It also detects the available wlans (displaying their ssids)

But, i never did get it to work when i try to connect to a wpa2-protected 
wlan. (never tried open or wep wlans yet).
Could you please assist in how to achieve a connection? Any help is 
appreciated...

(other things done already:
- i compiled the driver rtl8192su in the more recent kernel release 2.6.34 
and installed it. This one already got my usb-id included, so no further
changes to the code necessary. compiling, installing and using on my amd64
mandriva (still running kernel 2.6.33) had the same effects as above - 
scanning wlans is ok, connecting to a wpa2 protected wlan does not work)

As a last resort i tried the original realtek driver, compiled this stuff 
and had a kernel panic when inserting the usb stick. According to your 
previous posts, this might be due to the pointer problems on an amd64 
system as you pointed out.
)

So, any ideas how to proceed?
Thanks,
 Claus
