Support for MicroNext MN-WD550M Wireless USB 2.0 Adaptor

I was recently testing an f14 install on an old laptop without wifi
hardware - so I bought a small usb wifi adapter (MicroNext MN-WD550M
Wireless USB 2.0 Adaptor) and this is recognised when plugged in:
Bus 001 Device 002: ID 0bda:8171 Realtek Semiconductor Corp. RTL8188SU
802.11n WLAN Adapter

However it was clear that there was no driver support for this device
in the kernel.

There is a Realtek driver available at:
<a href="http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&amp;PNid=48&amp;PFid=48&amp;Level=5&amp;Conn=4&amp;DownTypeID=3&amp;GetDown=false&amp;Downloads=true#RTL8188SU" title="http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&amp;PNid=48&amp;PFid=48&amp;Level=5&amp;Conn=4&amp;DownTypeID=3&amp;GetDown=false&amp;Downloads=true#RTL8188SU">http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&amp;PNid=48&amp;...</a>

I downloaded the linux driver version 2.6.6.0 from 2010/12/17 and
untarred the files - and then used the standard make/make install to
build. This works nicely.

The question I have is whether there is likely to be any upstream FOSS
support for this very neat little wireless adapter so that it becomes
plug and play in the future? Is this being developed or is it all
proprietary?

Thanks

See drivers/staging/rtl8192su/r8192U_core.c, did you try that?

I notice that in rpmfusion free there is a kmod-staging package which
seems to have r8192s_usb.ko and r8192u_usb.ko in it - I guess that
this may work, but there is presumably still a need to include the
firmware file in /lib/firmware which is proprietary but at least this
would allow a yum update when the kernel updates and (maybe with a
small delay) get the new driver from the new associated kmod?

I suppose the mainstream Fedora kernel won't include the staging
drivers since they would be possibly unstable?

Just a delayed update on this issue.

I did install the kmod-staging-PAE package from rpmfusion, and also
pulled the RTL8192SU firmware directory from the Realtek web site (was
in a zipped file with drivers and other files)

Once that was done the dongle worked just fine.

I wonder how long it will be before the RTL8192SU driver will be
regarded as stable enough to go into mainstream? This works without
any problems at all for me. Or is that a question to ask in the
kernel list?

My guess is never, given the low amount of work on the staging wifi
drivers in general and the utter steaming piles of poo that they are.
But I've been wrong before.

Thanks - I was not aware of this - will try when I get some time over
the next few days....
