Hi,

I've just committed urtwn(4) to -current.
urtwn(4) is a driver for Realtek RTL8188CU/RTL8192CU USB 2.0
802.11b/g/n adapters.
It is currently enabled in i386 and amd64 GENERIC kernels.
Notice that it does not support the RTL8192SU devices which
are different.
The adapter requires a firmware which is available as a package
here: http://damien.bergamini.free.fr/packages/openbsd/\
urtwn-firmware-1.0.tgz

The driver has been tested with a Hercules HWNUp-150 adapter
but it should work with the Edimax EW-7811Un too.

Please report if you have such a device.

Damien
