Yes, I was able to test it.  I followed instructions from this site:
http://blog.xff.lt/2009/12/28/canyon-cnp-wf518n2-usb-wireless-linux/

I added the ID

diff --git a/drivers/staging/rtl8192su/r8192U_core.c b/drivers/staging/rtl8192su/r8192U_core.c
index 6f424fe..bec729f 100644

 };
 

Then I downloaded the driver from
http://xff.lt/stuff/canyon-wifi/rtl8192se_linux_2.6.0013.1204.2009.tar.gz

I took rtl8192sfw.bin from it and put it to /lib/firmware/RTL8192SU (not
RTL8192SE as in the archive).

I was able to load the driver, bring the interface up and scan.  I could
not connect to an AP with CCMP for some reason:

# wpa_supplicant -c /etc/wpa_supplicant/mike1.conf -i wlan29 -D wext

Association request to the driver failed

But I was able to connect to an unsecured AP:

I could also use the firmware called rtl8192sfw492.bin by renaming it to
rtl8192sfw.bin.
